摘要
介绍了一种新型结构的全固化二次谐波（ＳＨＧ）蓝光激光器．该器件用波长８６０ｎｍ的激光二极管作基频光源，采用ＫＴＰ晶体作为非线性倍频器并装在半共焦谐振腔内．由一个偏振器与一个λ／４波片组成光隔离器，而偏振器的一个端平面与一个球面输出镜组成半共焦腔．可获得功率２ｍＷ、波长４３０ｎｍ的蓝光激光的稳定输出。
In this paper , a kind of new structure of all solid state SHG blue laser with an external resonant cavity containing a nonlinear crystal is presented. Laser diode at 860nm is used as a fundamental frequency laser source and nonlinear crystal KTP is used for the frequency doubler. The optical isolator is comprised of a polarizer and a waveplate at λ /4. The half confocal resonator consists of one of end planes of the polarzer and spherical mirror. Stable operation of blue laser of output power of 2mW at 430nm can be obtained, and the distribution of SHG laser intensity is a Gaussian beam.
