摘要
为了提高Nd:GdVO4晶体直腔式蓝光激光器的热稳定性,本文在分析了端面泵浦情况下Nd:GdVO4(钒酸钆)晶体的热透镜效应,着重讨论了447nm蓝光激光器的输出功率波动与热透镜焦距之间的关系。与此为依据,在传统基模动态稳定腔设计方法基础上加以改进,借助MATLAB数学软件及Matrix Laser谐振腔设计软件,通过对谐振腔腔长、输入和输出镜曲率半径及腔内各个元件所处位置等参数进行优化。通过模拟及实验结果证明按此方法所设计的谐振腔具有良好的动态热稳定性。
For enhancing stability of the Nd：GdVO4 linear cavity blue laser,the thermal lens effect of Nd：GdVO4（gadolinium vanadate） crystal was analyzed with diode end-pumped.It focused on the relationship between the output power and thermal lens focal length of 447 nm blue laser.By improving the method of dynamic stable resonators and using MATLAB and the Matrix Laser,the parameters were optimized such as length of the resonant cavity,the radius of curvature of the input/output mirror and location of the various components in the cavity.The result of the imitation and experiment shows that the cavity has a good dynamic thermal stability.
