%X 通过激光二极管(LD)泵浦Nd:YAG产生1064 nm、1319 nm、1338 nm基频光，利用KTP晶体第二类相位匹配获得波长分别为589/593 nm的和频激光输出。从Nd:YAG晶体能级跃迁特性出发，揭示了Nd:YAG作为工作物质可以产1319/1338 nm激光的可能性。通过非线性光学转换频率及相关理论，分析了产生双波长和频输出的原理，同时也为多波长激光器的研究提供了参考。<br />
Laser diode (LD) pumps Nd:YAG to produce 1064, 1319, 1338 nm fundamental frequency light. The second type of phase matching of KTP crystal is used to obtain the sum-frequency laser output with wavelength of 589/593 nm. Based on the energy level transition characteristics of Nd:YAG crystals, the possibility that Nd:YAG can produce 1319/1338 nm laser as a working substance is revealed. By means of nonlinear optical conversion frequency and related theories, the principle of generating dual-wavelength and sum-frequency output is analyzed, which also provides a reference for the research of multi-wavelength lasers.
