Research On Laser Characterization Of Diffusion Bonding Nd：yvo4/yvo4 Composite Crystal

为改善高功率激光器激光工作物质的热效应，采用一种热效应较小的复合晶体Nd：YVO4/YVO4，利用z型折叠腔，研究了在高功率激光二极管端面泵浦的情况下复合晶体的激光特性。当泵浦功率为24．65W时，获得了12．5W的1．06μm红外输出，光-光转换效率达到50．7％；当泵浦功率为17W时，获得了6．38W的绿光输出，光-光转换效率为37．5％．

The output properties of a diode-pumped Nd：YVO4/YVO4 composite crystal laser at 1.06μm and frequency-doubling 532nm light with a ＂Z-shaped＂ folded cavity were studied. With the incident pump power of 24.65W, an output power at 1.061am of 12.5W was achieved, giving an optical conversion efficiency of 50.7%; With the incident pump power of 17W, 6.38W green light was generated, resulting in an optical conversion efficiency of 37.5%.
