The thermal lens model of the working cavity is used to analyze the effect of the laser cavity resonator configuration on the thermal lens and the stable region. The feasibility of adjusting the thermal effect by changing the cavity configuration is discussed. In the experiment, : YAG laser theory has been verified to achieve the thermal lens power and the stability of the distribution of the regulation.
