Method for realizing continuous light degenerate cavity laser by using thermal lens effect

The invention discloses a method for realizing a continuous light degenerate cavity laser by using a thermal lens effect. A continuous light degenerate cavity laser is realized by utilizing a thermal lens effect, and spatial partially coherent light can be generated through a variable 4f system. Continuous laser output of low-space coherence light is generated and achieved through the degenerate cavity, meanwhile, the thermal lens effect can be solved, the laser beam quality and the mode number can be improved, and a new light source is provided for the fields of illumination, optical communication and the like. 本发明公开了一种利用热透镜效应实现连续光简并腔激光器的方法。利用热透镜效应实现连续光简并腔激光器，并且可以通过变式4f系统产生空间部分相干光。本发明利用简并腔产生并实现了低空间相干性光的连续激光输出，并且同时可以解决热透镜效应提高激光器光束质量和模式数，为照明、光通信等领域提供了一种新光源。
