Abstract

A high efficient continuous wave diode-pumped Tm:YAP laser at room temperature was presented in this paper. Tm:YAP crystal with doped concentration of 4 at % was c-cut and had a cross section of 3 × 3 mm2 and length of 5 mm. Using double-passing-pumped cavity structure, under the pump power was 25.5 W, the highest output power reached 8.5 W by use of 10% output coupling, corresponding to optical conversion efficiency was 33.3% and the slope efficiency was 44.5%. The laser wavelength was 1936 nm with FWHM of 4 nm.
