He-Cd激光器工作特性与可靠性的实验研究

Experimental study on performance characteristics and reliability of He-Cd laser

通过设计新型结构的He-Cd激光器,并对腔长为600 mm和1000 mm的He-Cd激光器的工作特性进行了实验研究,分别获得了波长为442 nm和325 nm的激光输出,功率稳定性为2%/h,激光噪声为5%,工作寿命大于6000 h。

A new structure of He-Cd laser has been designed and experiments have been carried out to study the performance characteristics of two He-Cd lasers with the cavity lengths of 1000 mm and 600 mm respectively.The laser outputs with the wavelength of 442 nm and 325 nm have been generated accordingly.The power stability is ±2%/h,the laser noise is 5%,and the operating lifetime would be longer than 6000 h.
