Abstract

In order to study the influence factors of output power of Cr,Tm,Ho:YAG lasers, the variation of laser pumped threshold and output power were obtained using the cooling of water temperature to change the controllable factor. The relationship among the cooling temperature, frequency and power was analyzed. The results show that laser threshold increases with the rise of temperature and frequency. The increase of cooling temperature and repetition frequency will result in the decrease of laser output efficiency. When repetition frequency is 20Hz, output power of laser reaches 10.1W, output power of fiber end is 7.3W and total coupling rate is 72%. With single pulse energy of 2.0J~2.5J and repeat frequency of 20Hz~25Hz, Cr,Tm,Ho:YAG laser can achieve the desired result of crushing human kidney stones.
