设计了一种新颖的金属筒式加热器，使气体激光放电管轴向温度分布均匀。实现了缓冲气体流动的溴化亚铜激光器功率增长２倍，效率达到１％，在激光输出平均功率９Ｗ水平上持续稳定运转，最大平均功率为１０．６Ｗ。 A novel metal cartridge heater is designed to make the axial temperature distribution of the gas laser discharge tube uniform. The cuprous bromide laser with buffer gas flow increased by 2 times and the efficiency reached 1%. The average output power of laser beam kept steady at the average power of 9W with the maximum average power of 10.6W.
