摘要
采用线宽0.26 nm的Littrow外腔巴条半导体激光器泵浦增益长度8 mm缓冲气体为80 kPa甲烷的铯(Cs)蒸气室，在Cs蒸气室温度120 ℃时，我们获得了394 mW的894.6 nm线偏振Cs蒸气激光，光光效率7.4%，斜率效率11.2%，阈值功率为1.72 W。
Abstract
Pumped by a laser diode array with an external cavity of Littrow, whose linewidth is 0.26 nm, a cesium vapor laser is obtained using the cesium cell filled with methane of 80 kPa. At 120 ℃ of the cesium vapor cell, laser with output power of 394 mW and wavelength of 894.6 nm is realized. The laser’s optical efficiency is 7.4% while the slope efficiency is 11.2% and the threshold is 1.72 W.
