【Abstract】 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.更多还原
