Dysprosium-doped PbGa2S4 Laser Generating at 4.3 um Directly Pumped by 1.7 um Laser Diode
Original language description
In this Letter, we demonstrate the pulsed and CW operation of the Dy:PbGa2S4 laser directly pumped by the 1.7 ?m laser diode. In the pulsed regime (pulse duration 5 ms; repetition rate 20 Hz), the maximum mean output power of 9.5 mW was obtained with theslope efficiency of 9.3% with respect to the absorbed pump power. The generated wavelength was 4.32 ?m, and the laser beam cross section was approximately Gaussian on both axes. Stable CW laser generation was also successfully obtained with the maximumoutput power of 67 mW and the slope efficiency of 8%. Depopulation of the lower laser level by 1.7 ?m pump radiation absorption followed by 1.3 ?m upconversion fluorescence was demonstrated. These results show the possibility of construction of the compact diode-pumped solid-state pulsed or CW laser generating at 4.3 ?m in the power level of tens mW operating at room temperature.
