Abstract
The thermal properties of the grazing-incidence slab laser are investigated when cooling with a novel composite method, both conducted cooling and air cooling. The 3D temperature distribution and the correspondent thermal lensing effect were analytically modeled and numerically calculated. The absorption saturation and stress-optic effect were taken into account in the modeling. The influence of the parameters of the laser on the thermal lensing effect were investigated in detail. The results show a lower temperature and weaker thermal lensing effect for the composite cooling than for the traditional contaction cooling.
