Abstract

In order to alleviate the thermal lens effect effectively,based on the matrix optics,thermal lens effect in a flashpumped long-pulse green laser was analyzed with matrix transformation of Gaussian beam and a V-type cavity insensitive to thermal lens was designed.It was analyzed in theory and verified in experiments.The results show that it is reasonable to select parameters according to the matrix transformation of the Gaussian beams and the analytical simulation.This result is helpful for the alleviation of thermal lens effect and the improvement in performance of high energy medical lasers.
