摘　　要：为了演示低功率高斯激光条件下的热透镜效应,采用酱油作为研究介质,设计了简易、低成本、安全可靠、可控性好的可视化装置,来观察该非线性光学效应,采用光学成像法与高斯光束变换法测量热透镜等效焦距,通过比较验证,得到的结果接近,证明了这两种方法的可行性.Using soy sauce as a research medium,a simple,low-cost,safe,reliable,and controllable visualization device was designed to demonstrate the thermal lens effect under low-power Gaussian laser conditions.The equivalent focal length of the thermal lens was measured by optical imaging and Gaussian beam transformation methods.The results of the two methods were the same through comparison and verification.
