摘要
采用半导体抽运腔内倍频的方法，获得了可满足医疗应用的瓦级全固态561 nm黄光激光输出。在比较和分析了NdYAG激光晶体各主要谱线的激光参数之后，通过谐振腔膜系的设计抑制了增益较大的1064,1319和946 nm谱线的运转。通过对倍频晶体的合理选择以及晶体放置角度与匹配温度的合理控制，在13.5 W的808 nm抽运功率下，实验获得了1.41 W的561 nm单一谱线的黄光激光输出，光光转换效率为10.5%。
Abstract
The high power output of medical all-solid-state 561 nm yellow laser is achieved by the method of semiconductor-pump intracavity frequency doubling. After the comparison and analysis for laser parameters of the main lines parameters of the NdYAG laser crystal, the high-gain 1064, 1319 and 946 nm line operations suppressed by the membrane system design of the resonator cavity. Through the rational choice of the nonlinear crystal and the reasonable control of crystal placement angle and matched temperature, the single line of 561 nm output is obtained. The output power is 1.41 W at the incident pump power of 13.5 W, with the light to light conversion efficiency of 10.5%.
