采用 1W国产半导体激光二极管抽运Nd∶YVO4 ,Ⅰ类临界相位匹配LBO晶体腔内倍频 ,获得了 74mW的6 71nm红激光输出的实验结果。分析和实验表明 ,LBOⅠ类临界相位匹配是获得高效率倍频红光输出的实用方法。
The experimental results of the output of 671nm red laser with a wavelength of 74mW were obtained by using a 1W domestic semiconductor laser diode to pump Nd: YVO4 and type Ⅰ critical phase matching LBO crystal. Analysis and experiment show that the critical phase matching of LBO Ⅰ is a practical method to obtain high efficiency doubled red output.
