摘    要:报道了一种激光二极管抽运Nd:YVO4晶体、腔内Ⅰ类临界相位匹配LBO和频、连续波输出的全固态橙黄色激光器的设计和实验结果。橙黄色激光由Nd:YVO4晶体的1064nm和1342nm谱线腔内和频产生,输出波长为593.5nm。实验采用了双镜谐振腔结构,在1.6W的808nm注入抽运功率下,获得了最高功率为84mW连续波TEM00的橙黄色低噪声激光输出,光-光转换效率为5.3%,光束质量因子M21.2。实验和分析表明,采用激光二极管抽运Nd:YVO4晶体、LBOⅠ类临界相位匹配腔内和频是获得橙黄色激光的实用方法,并可以应用到Nd:YVO4晶体的其它谱线或具有多条谱线的其它激光增益介质,获得更多不同颜色的单谱线激光输出。

关 键 词:激光二极管抽运  腔内和频  全固态  橙黄色激光

Abstract:A fiber-coupled laser diode pumped Nd:YVO4 crystal,typeⅠ critical phase matching LBO crystal intra-cavity sum frequency mixing by 1064nm and 1342nm,orange-yellow laser at 593.5nm was reported.By using a two lenses-cavity resonator,with injection pump power of 1.6W,TEM00 mode orange-yellow,low noise laser at 593.5nm of 84mW was obtained at last,and the optical conversion efficiency was 5.3%,its M2 factor was less than 1.2.The experiments and analyses show that typeⅠ critical phase matching LBO crystal intra-cavity sum frequency mixing is an available technique for orange-yellow laser and it can be applied to other transition wavelengths in Nd:YVO4 or other laser with different laser gain crystals to obtain more all-solid-state lasers with different single wavelength.
Keywords:LD p umped  intra-cavity sum frequency  all-solid-state  orange-yellow laser
