研制成一台输出功率为百瓦级的铜蒸气激光器,其放电管长度为220 cm,内径为6.5 cm,脉冲重复频率为5 kHz,最大输出功率为106 W,效率为1%。给出了激光输出功率与放电参数的关系,通过与小口径(D<6 cm)放电铜蒸气激光器比较,阐述了大口径铜蒸气激光器的一些物理特性。

A large bore copper vapor laser with a 6.5 cm bore and 220 cm long discharge tube has been developed in this laboratory. A maximum output power of 106 W was achieved. The laser operated at a repetition rate of 5 kHz at the 510.6 nm and 578.2 nm lines of atomic copper. The efficiency reached 1% when the laser operated at the average output power of 95￣100 W. Some relations between output power and discharge parameters are prestented in this paper. An explanation of the physical characteristics of the large-bore CVL through a comparison of the large-bore CVL to the small-bore CVL is given.
