578.5 nm End-Pumped Passively Q-switched Raman Yellow Laser
摘要
研制了一种基于Yb 3+∶YAG/Cr 4+∶YAG/YAG键合晶体的激光二极管端面泵浦被动调Q拉曼黄光激光器。由键合晶体产生的被动调Q基频激光依次通过拉曼晶体YVO4和倍频晶体KTP,最终输出波长为578.5 nm的激光。采用耦合腔结构降低拉曼光和倍频光的损耗,采用标准具抑制双波长运转以提高倍频的转换效率。实验结果表明,当入射波长的泵浦功率为9.51 W时,可以检测到功率为183 mW、波长为578.5 nm、脉冲宽度为6.537 ns、重复频率为6.542 kHz的黄光。
Abstract
A laser diode end-pumped passively Q-switched Raman yellow laser based on Yb 3+∶YAG/Cr 4+∶YAG/YAG composite crystal is developed in this work. The passively Q-switched fundamental-frequency laser generated by the composite crystal passes through the Raman crystal YVO4 and the frequency-doubling crystal KTP, and finally obtains a laser output of 578.5 nm. A coupled cavity structure is used to reduce the loss of Raman light and frequency-doubled light, and an etalon is used to suppress dual-wavelength operation to improve the conversion efficiency of frequency-doubling. Experimental results show that when the pump power of the incident wavelength is 9.51 W, yellow light with a power of 183 mW, a wavelength of 578.5 nm, a pulse width of 6.537 ns, and a repetition frequency of 6.542 kHz can be detected.
