To get the relation between output pulse energy and laser crystal temperature about a flash lamp pumped Cr,Tm,Ho:YAG laser with a plane-plane cavity,the temperature distribution of the laser crystal was calculated for the different cooling temperatures and pump frequencies by means of finite element method.At 15℃ and 5Hz,the maximum output pulse energy and slope efficiency were 217mJ and 1.4% respectively.However,at 10Hz,the maximum output pulse energy and slope efficiency were 56mJ and 0.9% respectively.The results show that pump threshold increases and output efficiency decreases with the increase of temperature and frequency.
