摘要
在几何光学的基础上设计了变反射镜谐振腔激光器 ,并利用衍射光学理论 ,将腔内光束模式满足的方程表为易于通过快速傅里叶变换迭代求解的形式 ,以高斯型、超高斯型变反射镜为例 ,求出激光在反射镜、输出镜、近场、远场光场分布的三维数值解 。
On basis of geometry optics,we designed unstable resonators with Gaussian and super-Gaussian variable reflectance mirrors.The mode equations in the cavity is obtained by FFT expressions so as to be easily solved.The 3-D optic intensity distributions in near and far field,as well as reflecting from reflectors,output mirrors,are numerically calculated.These results can be used as available references for design of unstable resonators with variable reflectance mirrors.
