Experimental study on the 1.94-μm laser performance of c-Cut Tm:YAP crystal with various doping concentration
The influence of the thulium ion concentration on the 1.94-μm laser performance of c -cut Tm:YAP crystal was investigated in this paper. Three crystals with 3, 4, and 5% Tm 3+ (atom concentration) were examined at 18°C. Our experimental results showed that, the best power performance was obtained wi...

Summary: | The influence of the thulium ion concentration on the 1.94-μm laser performance of
c
-cut Tm:YAP crystal was investigated in this paper. Three crystals with 3, 4, and 5% Tm
3+
(atom concentration) were examined at 18°C. Our experimental results showed that, the best power performance was obtained with the 4% Tm:YAP crystal. By using 24.8 W of incident pump power at 795 nm, a maximum of 7.5 W of output power was obtained. The slope efficiency was 48.8%, corresponding to diode-to-Tm conversion efficiency of 30.2%. |
