摘　　要：报道了一种单LD泵浦Nd:YVO4双晶体腔内和频实现黄光激光的有效方法,并对其进行了理论分析、实验装置的设计和实验验证。该装置由半导体激光器、光学耦合系统(CO)、Nd:YVO4镀膜晶体、镀高反膜的平凹镜、镀增透膜的LBO、镀高透膜的全反镜组成。实验采用V型谐振腔,在中心波长为808.7 nm、5 W抽运功率下,利用Ⅰ类临界相位匹配LBO作为和频晶体,获得了244 mW、593 nm的黄光输出,光-光转换率为4.9%,激光不稳定度为5%。实验结果表明:采用V型谐振腔进行腔内和频,可以获得593 nm的黄光激光,并且结构紧凑、转换效率高,可以应用到很多种和频激光器中。An efficient method of 593 nm yellow laser with a single LD pump source and Nd：YVO4 double crystals was reported. The theory was analyzed, the experiment device was designed and the experiment result was verified. The device was composed of laser diode, optical coupling system, Nd：YVO4 crystals, plan-curved mirror, LBO and totally reflecting mirror. By using V-type resonant cavity, with in cident pump source with the 5 W power and the 808.7 nm wavelength, the experiment adopts type I critical phase-matched LBO as sum-frequency crystal, and the 244 mW yellow laser at 593 nm was obtained. The optical to optical conversion efficiency was 4.9%, the laser instability was about 5%. The experiment result shows that the intra-cavity sum-frequency in V-type resonant cavity can obtain 593 nm laser, and the method has structure compact and high conversion efficiency advantages, and can be used in many sum-frequency laser.
