Employing a fiber-coupled diode-laser with center wavelength of 852.25 nm and line width 0.17 nm, experimental investigation on diode-end-pumped cesium (Cs) vapor laser stably operated at continuous-wave (CW) pulse regime is carried out. A 5 mm long cell filled 60 kPa helium 20 ethane used as medium. Using an output coupler reflectivity 48.79%, 1.26 W 894.57 CW obtained incident pump power 4.76 W, corresponding optical-optical efficiency 26.8% slope-efficiency 28.8%, respectively. The threshold temperature 67.5 °C. Stable pulsed maximum average 2.6 repetition rate 76 Hz, the can be extend to 1 kHz 18 μs.
