The effects of different pump power, super-Gaussian order, spot radius and crystal size on the temperature field of Yb:YAG crystal with variable thermal conductivity are analyzed. The results show that the pump power is 60 W, the super Gaussian order is 5, and the spot radius is 400 渭 m, the pump power is 8%, the crystal radius is 4 mm, and the thickness of 0.5mm is 4 mm, and the pump power is 60 W, the thickness of the crystal is 4 mm, and the laser spot radius is 400 渭 m. When the thermal conductivity of the crystal is regarded as constant and variable respectively, the maximum temperature rise at the pump end is 52.15 鈩，
