Ultraviolet laser's application
With the rapid development of semiconductor laser industry, the research of all solid state laser based on semiconductor laser as pumping source has made huge progress. Semiconductor laser pumped all solid state infrared laser and the obvious wave band's laser have already obtained the massive applications in many regions, for example, laser condition resistance, memory chip maintenance, the solar energy battery marking, laser marking and so on.
Comparing with the tradition infrared and obvious wave band's laser, the advantage of ultraviolet laser is short wavelength, concentrated energy, high resolution, slight focus point to sub-microsecond magnitude. In addition, ultraviolet laser has higher absorption coefficient on some special material, therefore the ultraviolet laser can be applied in the silicon and the ceramic material processing, the sapphire crystal marking, copper level of the multi-layered PCB circuit wafer punching.
The ultraviolet laser has the widespread application prospect in material processing, ultraviolet curing, lithography, photolithography, medical service, spectral analysis and scientific research.
For a long time, excimer laser plays a leading role in the application of UV “cold working”. But with the development of all solid state laser, it becomes more effective processing method in this region.
UV laser can be widely used in other area. For example, CW low power laser source nearby 355nm is needed by Disc control processing. 355nm laser, as tripled frequency of 1064nm, is an attractive kind of laser source.
Changchun New Industries Optoelectronics Tech. CO., Ltd. (CNI laser) produces two kinds of UV laser which have already been widely used in ultraviolet processing and so on. One kind is 266 nm Q-switched ultraviolet laser, with the speciality of single pulse energy 50 uJ, pulse duration 10 ns, and average power 500mW. The other kind is 355nm Q-switched ultraviolet laser, with the speciality of single pulse energy 150uJ, pulse duration 10ns, average power 1.5W.
