摘要：
The thermal lens effects in Tm:YAP laser are analyzed by solving the Poisson equation with finite difference method. The thermal focal lengths measured are in the range of 40 - 90 mm at the pump power of 16 - 34 W, consistent with the simulation results. The temperature contribution coefficient (the linear coefficient between the maximum temperature in the laser crystal and the pump power) of 1.19 K/W is also obtained. The convex lens and piano-concave mirror thermal lens compensation methods are proposed and applied to a high power pumped Tm:YAP laser.
