| 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. |
