Abstract

A high-efficiency continuous-wave Tm:YAG laser end-diode pumped at room temperature is presented in this letter. The highest output power reaches 6.37 W when the incident pump power is 18.9 W. The optical conversion efficiency is 33.7% and the slope efficiency is 42.8%. The wavelength of the output laser is shifted to the short wavelength with an increase in the transmission of the output couplers. At a fixed cavity length, the composite Tm:YAG shows its dominance for its higher efficiency and higher quantum efficiency compared with the noncomposite Tm:YAG.
