Laser manufacturing technology is based on the physical interaction between the high energy of the laser and the material, and the material is vaporized, ablated, modified to achieve the material processing effect.
Nowadays, laser processing has rapidly entered all walks of life, and it is still dominated by metal material processing, accounting for more than 80% of the entire laser processing application. Since metals such as iron, copper, aluminum and corresponding alloys are hard materials, they have a good effect on the laser, so they are easy to apply to laser processing. For some common metal laser cutting and welding applications, you may only need to know the corresponding optical power, and the research requirements for processing are not very strict.
But in fact, many non-metallic materials are used in life and high-end manufacturing, such as soft materials, thermoplastic materials, heat-sensitive materials, ceramic materials, semiconductor materials, and brittle materials such as glass. If these materials are to be processed by laser, the requirements for beam properties, degree of ablation, and control of material damage are very strict, and ultra-fine processing is often required, even at the micro-nano level. It is often difficult to achieve results with common infrared lasers, but ultraviolet lasers are a very suitable choice.
UV laser technology use diversity.
UV lasers refer to the output of the light beam located in ultraviolet spectroscopy, naked eye, currently used in industrial ultraviolet lasers with solid crystal ultraviolet lasers and the gas ultraviolet laser. Three times the infrared full solid laser can be used to obtain ultraviolet laser output, with a total wavelength of 355 nm, and the current pulse width has been successfully developed from nanosecond to the picosecond level. The gas ultraviolet laser is common is the excimer laser, mainly used in ophthalmology, chip photolithography, and so on. In recent years, the fiber laser has gradually developed the products of ultraviolet bands, with the most representative of nanosecond ultraviolet fiber lasers.
Since UV lasers lose a lot of heat during frequency doubling conversion, and the cost is still high, it is still difficult to achieve higher power at present. Ultraviolet laser is often regarded as a cold light source, so ultraviolet laser processing is also called cold working, which is very suitable for the processing of brittle materials.
Common Brittle Materials Processing with UV Lasers.
Glass is a material that is widely used in life. From water glasses, wine glasses, containers to glass accessories, pattern making on glass is often a difficult problem. Traditional processing often results in high glass damage rates. UV lasers are very suitable for glass surfaces. Marking, pattern making, and can achieve ultra-fine production.
The ceramic material is used in large quantities of construction, utensils, ornaments, but in facts, ceramics have many applications on electronic product devices. For example, there are mobile merchants launched a ceramic rear cover, in the field of mobile communications, optical communication, and electronic products. Ceramic ferrule, ceramic substrate, ceramic package base and ceramic cap plates of fingerprint recognition systems, etc.
UV laser wafer cutting: The surface of the sapphire substrate is hard, and the general knife wheel is difficult to cut, and the wear is large, the yield is low, the cutting channel is greater than 30 μm, not only reduces the use area, but also reduces the product production. UV laser cutting wafer can achieve high precision cutting, smoothing incision, and the improvement rate is greatly improved.
