Laser Surface Amorphization

In this study, a cadmium sulfide (CdS) line with a diameter of 204 nm and a length of 15 μm was used as the core design of the optical cavity (Fig. 1). The high refractive index of the nanowires causes the incident light to have a high reflectivity factor at the end face and be guided by the nanowires. This arrangement forms the Fabry-Burrow cavity, which, when activated by an external light source, forms a laser. The laser wavelength thus formed depends on the refractive index around it. By measuring the wavelength of the most powerful laser output, the refractive index of the liquid immersed in the nanowires can be determined.

There are a variety of methods for surface nanocrystallization of materials. There are a large number of surface nanocrystallization technologies. It is a surface layer which can realize the nano-characteristics by means of laser surface treatment technology and nanometer technology. It can be collectively referred to as laser surface nanocrystallization technology; More generally referred to as laser nano-surface engineering technology, is directly or mainly the use of laser this specific technical means to directly change or add material to change the surface of the solid material is treated, the composition or structure, so that the formation of nano-crystal Grain or a certain nanoparticle composition of the surface layer. Or the use of laser etching, laser embossing, laser hair, laser micro-nano modeling and other means to achieve nano-structure on the surface of the material.

Analysis of China ‘s Laser Industry

In fact, blue laser pointer processing equipment in addition to the ever-increasing demand for power, has been committed to the quality of equipment assurance and technology development. The cost-effective ratio of laser processing equipment refers to the continuous reduction of product prices relative to performance guarantees, so that customers really use “cheap” products, rather than to sacrifice product performance, reduce equipment configuration to reduce the price, nor is it simple The pursuit of processing efficiency at the expense of processing stability. Laser processing equipment stability and efficiency is a contradiction, the product in the industry and the application market has been widely recognized, the formation of the brand, because the equipment has been cutting the stability of the first place, and the stability of the main indicators are Equipment failure rate.

In recent years, domestic and international laser industry mergers and acquisitions frequently, because the laser industry low level of repeated investment seriously lead to overcapacity and industrial transformation and upgrading of the demand coexist. Before 2010, high-power green laser pointer equipment industry also belongs to high-profit high-return industry. However, due to investment and technical threshold is not high, a lot of money into the market quickly showed a vicious competition situation. However, many companies have overlooked that the industry in fact the process threshold is high. Do not attach importance to process development, in the homogeneous competition environment, in order to pursue a lower price advantage, reduce equipment configuration and thus reduce the performance of equipment becomes inevitable, which led directly to a group of enterprises died, a number of enterprises overcapacity. While the excess capacity to make the advantages of mergers and acquisitions to reduce the cost of mergers and acquisitions began to prevail this stage. On the other hand, with the transformation and upgrading of the Chinese market continues to deepen, as the transformation and upgrading tool industry, the laser industry into a period of rapid development.

PLC control and computer control in two ways to choose, the machine output power is stable, reliable performance, compact structure, beautiful appearance, easy to operate, with coaxial, paraxial gas protection device to improve the welding quality; and optional high power laser cutting Head, for cutting to expand the processing range.

Since the second quarter of this year, the market demand for equipment, the rapid increase in power, and soon from 4KW, 6KW to 8KW. Has been the customer’s demand to upgrade to more than million watts, mainly due to customer processing capacity of laser processing equipment and processing efficiency requirements. On the one hand is the original customer with the same material with the thickness of the material cutting efficiency requirements, on the other hand is constantly emerging new areas of laser technology processing needs, especially for ultra-thick processing of materials processing requirements to laser processing technology Alternative to other processing technology.

China’s manufacturing industry and intelligent manufacturing is still very far away from the industry 2.0 to industrial 4.0, China still has a long way to go. Germany’s industrial 4.0 has hard power, the US industrial 4.0 has soft power, while China’s industrial 4.0, 2.0, 3.0 and 4.0 are simultaneously developed. On the red laser pointer industry, whether it is the market demand or industry requirements, from the equipment automation requirements are still distance, and intelligent requirements, whether technical or market base are far worse. However, in new areas of new markets, the demand for automation equipment has increased significantly, especially in key industries and high-end customers.

The Perfect Combination of Robot and Laser Welding

Laser welding is the fastest growing field in laser processing technology. Laser welding is the high-intensity laser beam radiation to the metal surface, through the interaction of laser and metal, metal absorption blue laser pointer into heat to melt the metal after the crystallization of the formation of welding. Compared with the traditional welding method, the technology will bring many advantages:

The use of fiber optic transmission of laser, so that the energy source and processing equipment from the space separation can be difficult to achieve. The light energy generated by the laser can be transmitted through a very small diameter fiber to the far distance of the station, through the robot, to achieve the workpiece welding. A green laser pointer welding robot can replace three to four resistance welding robot, if the full use of laser welding technology, processing a body, in the tooling investment, welding parts preparation, material consumption, body seal and other aspects of the cost will be reduced by about 200 US dollars, Steel utilization can be increased by 50%.

The use of laser welding can save a lot of templates and tooling equipment, so that the workshop area by half, saving investment. In the automotive industry, as a vehicle key components of the body, its value accounts for about 20% of the car, the use of laser welding, can reduce the overlap width and some reinforcement components, but also can compress the body structure itself volume, The weight of the body can be reduced by 56kg. Similarly, for a large number of spot welding in the body transfer, if the welding of a welding head on the edge of the workpiece for welding, the flange width of 16mm, and laser pen welding is unilateral welding, only 5mm, the spot welding to laser welding, each car can save steel 40kg. With the traditional spot welding two pieces of 0.8mm steel stamping parts, an average of 20 points / min, welding torch is 25mm, the speed of 0.5m / min, with laser welding speed can reach more than 5m / min.

Power laser welding machine, host, power supply, table, refrigeration unit split design; the machine into my company’s new condenser cavity, the photoelectric conversion efficiency, excellent beam quality, reflective surface and cooling medium without contact, cavity Long life, easy to replace xenon lamp and no need to adjust the optical path. PLC control and computer control in two ways to choose, the machine output power is stable, reliable performance, compact structure, beautiful appearance, easy to operate, with coaxial, paraxial gas protection device to improve the welding quality; and optional laser cutting Head, for cutting to expand the processing range.

The Future Development of CO2 Laser

Power continuous CO2 laser marking machine laser: for the helicopter engine turbine blade with continuous laser cladding cracks and blade deformation problems in the 5kW continuous cross-flow CO2 laser, the use of new power control program, through software and related control, To achieve the pulse blue laser pointer power output to overcome the use of high-power switching power supply costs and stability problems and pulse modulation frequency up to 5Hz, modulation duty cycle can reach 5% to 100% when using 4kW peak power, 4Hz The results show that the heat affected zone is 50% lower than that of the continuous laser, and the hardness is increased by 5% after the cladding. The results show that the heat recovery zone is 50% , The interface with the performance of the base material is equivalent, no melting cracks and leaf deformation.

Compact long-life RF excitation waveguide CO2 laser: In order to make CO2 lasers in industrial processing and military have a wider range of applications, the use of aluminum alloy drawing profiles as a laser shell, plate mounted inductors instead of the traditional wirewound inductance structure and all-metal Sealing technology, etc., developed a compact long-life RF excitation waveguide CO2 laser. Can be continuously output or no higher than 20kHz modulation frequency pulse output, the maximum output power of 30W, the measured working life of more than 1500h, storage life of more than 1.5a The results show that the laser pointer has the characteristics of compact structure, stable output power, long working life, continuous and pulse modulation, and can be applied in military applications in addition to the processing of various materials.

Acousto-Optic Q2 Laser: In order to meet the requirements of laser ranging, environmental detection, space communication and laser-material interaction mechanism research, developed sound and light modulation QC02 laser. The main technical parameters of the output of the laser are analyzed and calculated by using the Q – ray pulse rate equation of the Q – switched pulsed laser. The method of acoustic and QCO2: laser optimization design is proposed. Conducted a validation experiment.

In addition to the original DC discharge (DC discharge) excitation technology, there are AC discharge (AC discharge), radio frequency discharge (RF discharge), microwave discharge, which are developed this year, a variety of new incentive technology, DC discharge and RF discharge. Different materials, different paths of laser cutting machine, welding, surface treatment, often require the green laser pointer beam to change the way of work at any time, sometimes requiring continuous output, and sometimes require pulse output waveform. In recent years there has been enhanced pulse output, so that processing performance improved significantly.

High current gas discharge in the current, voltage, gas temperature are high, glow discharge positive column area of the thermal instability and arc contraction and so on more serious. How to ensure the uniformity and stability of large volume glow discharge is one of the key technologies of high power carbon dioxide lasers. Our commonly used techniques include: the large volume of discharge divided into many small discharge areas were controlled; gas rapid flow instability of the disturbing factors in time to bring out the discharge area; increase the turbulence to increase the uniformity of discharge; increase pre-ionization or external Ionization source to increase the uniformity of discharge.

The pulse repetition frequency of the laser is lHz ~ 50kHz, the output laser pulse width is 180ns and the peak power is 4062W, which is basically the same as the theoretical calculation. The results show that: through the acousto-optic crystal (AO) optimization and reasonable design of the resonator. Can achieve a small CO2 laser marking machine laser high frequency, narrow pulse width, high peak power output, and through the raster selection line design and TTL signal control to achieve such a red laser pointer wavelength tuning and coding output.

Laser cutting, welding and other applications require excellent beam quality, especially after the focus of the beam as thin as possible. In high power lasers, carbon dioxide lasers are the best of the beam. In the high power state, the thermal distortion and thermal damage of the laser crystal output window and the total reflection mirror are often the key technical problems that limit the improvement of the laser power and the improvement of the beam quality. Substrate selection and cooling, polishing, ultra-fine car and other process problems is also very important.

Carbon dioxide laser electro-optical conversion rate is generally in the range of 10% -20%, which can be considered a high conversion rate. Most of the rest of the discharge power through the electronic and gas particles of the elastic collision of gas heating, temperature rise; for high power lasers, the gas temperature rise faster. When the working pressure temperature reaches 300 ℃, the laser pen light and the lower energy level of the carbon dioxide laser have no laser output because there is no particle inversion. The actual situation is the gas temperature is greater than 150 ℃, the electro-optical conversion efficiency has decreased significantly. For this reason, the device is required to be able to quickly and efficiently take away the heat of the discharge zone gas. There are two commonly used methods: gas convection cooling and diffusion conduction cooling.

Future upgrades include installation of htpow laser

Everyone has heard about the laser missiles, but few people know that there are laser bullets. Army laser pointer , which previously had between 5 to 10 kilowatt strength. It can be made up of batteries, capacitors, or flywheels, and would recharge between laser pulses.

Future upgrades include installation of a wind tunnel to study laser/material interactions of components. This laser will be far more powerful and will be designed to take out objects as large as ballistic missiles mid-flight. Which limits where you can stick a laser.

They often talk about the cost advantages of firing laser pointers to incinerate incoming enemy attacks (https://www.htpow.com/highquality-500mw-burning-waterproof-red-laser-pointer-p-1067.html) . The current state of the technology and to highlight the limitations of the upgraded laser. The Army hopes that once the laser technology matures.

Be proposed a two-kilowatt laser pointer with a penny-diameter beam designed to burn drones to a crisp.Lasers do not work in blinding rainstorms. If it’s been compromised by a major laser pointer burn through on the nose cone, aerodynamic forces should rapidly disassemble it.

The Army is dialing up its lasers, from 5 to 10 kilowatt weapons that torched quadcopters in successful. Yes it is good enough, and a near optimal solution for laser application on the battlefield.One possible shortcoming with a laser that I can see is that given its relatively low killing power.

The study has engineered a more cost-effective green laser pointer

Because it is laser-guided, it hits exactly where you’re oriented and aimed (https://www.htpow.com/high-powered-30000mw-blue-laserpointer-445nm-worlds-brightest-p-1027.html) . Summer is not when you should get laser, because when the skin is exposed to the sun. So many spas and other facilities do laser and may not be properly trained, so people are getting laser when they are not the appropriate candidate.

The laser light is as bright as 100 trillion watts of light when at peak power. It will offer free shooting in the laser arcade this weekend. It’s laser equipment has two lasers in one machine, and the laser use is based on the customer’s skin tone or hair color so the company can provide more personalized services.

He saw great potential with lasers in alignment. Knowing an unstable laser mount would yield inaccurate results. But uses for the laser didn’t grow to meet the hype. By firing the most powerful x-ray laser in the world at a vial of water.

This is one of many advancements that have been made recently in the field of green laser pointer technology. The newly-developed laser is tunable, which means that users can choose the colour of the laser themselves, within a broad range.

The study has engineered a more cost-effective green laser pointer design that outputs multi-color lasing and offers a step forward in chip-based lasers and miniaturization. The typical lifetime of the tube in an argon ion laser is roughly 10,000 hours. A ‘sharper’ laser increases the accuracy of whatever system it is put into by making it more precise.

Solid laser accounted for the largest share of the laser technology market based on type segment.The laser technology market for the commercial vertical is expected to grow at the highest rate.Nanosecond laser cataract surgery is being clinically used today and I believe is a very promising technology for tomorrow.

The laser technology of the Mona Lisa Touch has been around for about 5 years and is usually available.The force says it has launched a pilot project that will test the use of laser-aimed darts.Rotating a polarizer for excitation laser polarizations set to horizontal.

But doing a broader cleanup will require reaching deep into the bag of tricks, starting with the laser cannon.What he really wants to do is use the same laser array technology.To deliver the right color of light, Belkin’s team uses a laser.

And with the help of a fast laser that operates within the safety limit, the upgraded device can image the full cross-section of an adult rat 50 times per second.Therefore, finding that optimal set of laser parameters and choosing the right cost-effective technology is very important.
