Abstract

We elaborate a high-power, high-efficiency cw Tm:YAP laser dual-end-pumped by the laser diode. With 41.9 W pumping power, we obtain a maximum cw output power of 14.7 W at 1988 nm with a slope efficiency of 43.8%, corresponding to an optical conversion efficiency of 35.1%. At the maximum laser output, we measure a beam quality of M 2 ~ 1.9.
