The following first describes the basic composition of optical amplifiers and their characteristics, and describes an integrated, grating, wavelength conversion function l BIJ tongue fiber amplifier has excellent zoom features, now reached the practical level, it points to the recent wave multiplexing technology The development of optical communication systems constitute a big impact. With the high performance semiconductor lasers, semiconductor optical amplifier for basic research [1]. From semiconductor lasers possess the characteristics of view, that can be used to inject current incentives and miniaturization, are eager to semiconductor optical amplifiers widely used ultraviolet lasers. The price difference of green laster pointer is little actually. Ultraviolet (UV) laser field in a wide range of industrial micro-machining applications such as industrial parts marking, drilling, scribing, welding, cutting and micromachining of medical devices, electronic components, packaging, three-dimensional micro parts molding. In addition, in microelectronics, spectroscopy, optical data storage, optical control, atmospheric sounding, photochemistry, photobiology, space optical communications, laser-induced atomic fluorescence and UV absorption of the material (such as Si atoms induced fluorescence, frozen and control ) and medical and other fields also have a wide range of applications. Particularly in the industrial processing sector, due to the short wavelength UV laser and high photon energy characteristics of the focused spot can be smaller, while the high energy UV photons directly destroy the molecular bonds material, relative to the infrared laser, "melt" process, UV Laser processing is a "cold loss" effect. The RF technology of 100mW laser pointer is at the advanced level. This makes the process of size can be smaller, improved machining accuracy [4]. Describes the high-power ultraviolet (UV) laser application, reviewed the resulting UV laser and nonlinear optics to produce high-power ultraviolet laser for nonlinear optical crystal, is given in recent years, the most widely used high-power 355 nm and 266 nm solid-state UV lasers in the domestic and international research and look forward to a high-power solid-state UV laser development issues to be addressed and possible technical way. Laser diode (LD) pumped solid-state UV lasers and other types of UV lasers, compared with a high efficiency, high repetition rate, reliable performance, light weight, simple structure, the output beam quality, power stability and higher practical advantage of low prices. The smooth working of 10mW blue violet laser pointer should be ensured at first. Makes the LD-pumped solid-state lasers, UV light research is developing rapidly. Particularly good performance of UV nonlinear optical crystal and coating technology to improve, and in improving the optical mode and the laser pump light coupled into the laser crystal in the design optimization of the major achievements, enables high-power solid-state UV, high-efficiency, high beam quality, long-term stability and long life characteristics. Especially on 355 nm and 266 nm, represented by solid-state UV laser processing in the industrial area has been widely used. This article focuses on high-power 355 nm and 266 nm solid-state UV laser research at home and abroad as well as the research group in these two types of solid-state UV laser of the latest research results. The manager is showing the smooth working of 200mW Laser Pointer. Finally, prospects of high-power solid-state UV laser development and addressing the problems faced by the technical approach. Doubling (SHG), third harmonic (THG) is a non-linear optics, the most thorough study of the most important is the content, they are three-wave interaction, which two fundamental laser frequency is generated second harmonic light, three times frequency of the fundamental frequency light and second harmonic light generated third harmonic frequency, the basic principle shown in Figure 1. In essence, the process and frequency multiplier process is a special case, when ω = ω. The most commonly used 355 nm and 2 1 266 nm solid-state UV laser, for example, usually in the fundamental frequency by the 1064 nm infrared light through a multiplier, part of the 532 nm infrared light into green light frequency, the remaining fundamental frequency 1064 nm light and 532 nm 2 solid-state UV laser generation solid-state UV lasers based on the basic principles of optical mixing in nonlinear optics is based. The RF green laster pointer can get more customers.
