| Abstract: | A high power Tm:YAP laser device was reported. The laser gain medium was b-axis-cut YAP/Tm:YAP/YAP composite crystal rod. By using a LD module with a center wavelength of 795 nm for double-end pumping, when the temperature of the cooling water was set at 20℃, and the total pump power was 301.4 W, the linear polarized laser output of 1.94 m with a maximum of 109.5 W was obtained. The optical-to-optical conversion efficiency was up to 36.3% and the slope efficiency was about 45.8%, the measured beam quality of M2 factor was 3.8 at the highest output power condition. |
