Both made of small and medium-sized power and microchip lasers, but also made-kilowatt high-power solid state laser processing machine, and Q, the clamping a variety of ways. Also has a low light threshold, high gain, high efficiency, low 1064 nm loss, etc.; high optical quality, good thermal conductivity, high thermal shock resistance and mechanical strength features, making the Nd: YAG has become a continuous and pulse mode-locked laser is the most appropriate and commodities. 3 + 6 ND : 2.2.3 ND: YAG lasers Nd: YAG laser with Nd: YAG crystal as the working substance, it is a four-level system, and has a high quantum efficiency by the excited radiating advantage of the threshold is very small, and yttrium aluminum garnet crystal also has a high thermal conductivity, easy to heat. The customer till has some questions about the nonconformance ofgreen laser pointer.
Of Nd: YAG laser can not only single-pulse operation of a power more than 1000W, 5000 repetition frequency of the output peak power reached kilowatts or more per second, per second, dozens of high repetition rate can also contact operation. At present, Nd : up to several hundred watts of peak power Q-switched laser of the YAG laser repetition rate of the biggest losers .. Nd: YAG laser is widely used, it is mainly used in the processing for punching, cutting, scribing, welding, resistance of fine-tuning, marking and surface modification. 2.3 of LD-pumped solid-state lasers 2.3 2.3.1 of LD-pumped solid-state lasers advantages With the increasing development of semiconductor technology and mature, the laser diode in the power conversion efficiency, wavelength extension and operating life has been greatly improved. The workshop is preparing the improvement action table of green laser pointer.
Laser diode (LD) with high quantum efficiency, high reliability, long life, the emission wavelength of the laser medium absorption peak of good corresponding laser output beam quality characteristics, which makes the laser diode pump technology combined with each other to become laser an important breakthrough in pump technology, the rapid development of the pumped solid state lasers is becoming a trend. laser diode pumped solid state laser (Semiconductor, Diode-Pumped Solid State Laser) laser diode (Laser Diode) instead of flash to -pumped solid-state laser gain medium laser, both the advantages of semiconductor laser diodes and solid-state lasers, semiconductor lasers, small size, light weight, direct electrical injection to high quantum efficiency. A lot preparation ofgreen laser pointershould be done before the dispatch ofgreen laser pointer.
Can temperature by adjusting the composition and control Ga1-xAlxAs, the wavelength band that matches the commonly used solid-state laser material pumped; solid-state laser output beam quality, have a good time and spatial coherence, spectral linewidth and The beam divergence angle than the semiconductor several orders of magnitude. Therefore, the diode-pumped solid-state lasers can effectively select the pump wavelength, the laser medium absorption lines corresponding to LD can be used to pump with different activated particles solid-state laser material, rich in a coherent light source spectra, the band can cover 946nm to 2.01μm, to broaden the applications of solid-state lasers, laser diode pumped solid state lasers, high-efficiency, high beam quality, long life, full curing structure compact and light and other very prominent. The workshop makes the specific production plan the large orders ofgreen laser pointer.
Have wide applications in areas such as medical, communications, materials processing, entertainment and scientific research. Compared to gas lasers and lamp pumped solid state lasers, laser diodes ((LD) or laser diode array ((LDA)-pumped solid-state laser has a great advantage compared to gas lasers pumped solid state laser apparatus LD 7 near-infrared wavelengths can be used in optical fiber transmission, and high peak power, compact device features. Compared to the traditional flashlamp pumped solid-state lasers: First, the LD / LDA-pumped high-efficiency multi-doped Nd3 laser, for example: As the pump light a wide radiation spectrum and riveting ion absorption band matching bad, usually the lamp-pumped Nd : YAG laser efficiency is low and 3%, and thermal effects in high-power obviously, poor beam quality and stability. The expert group gives some suggestions for the technology improvement of green laser pointer.
