| Abstract: | The heat-capacity operation of a solid state laser is a novel method by which a high quality beam and high average power can be generated. This paper describes a diodes-pumped solid state heat capacity laser that produces average power of 300 W and a running duration of 5 s. In order to get a uniform gain distribution and acquire a fine thermal distribution to reduce the stress of laser material and to lengthen the time of output, numerical simulation was done to meet the operation conditions of laser . The experiment results show that the output power is up 300 W, the optical-optical efficiency is above 25%. |
