摘要

A high-efficiency narrow-band 2000 nm Tm: YAG ceramic laser that combines the advantages of in-band pumping at 1617 nm and volume Bragg grating for wavelength selection was demonstrated. Using an output coupler with 10% transmission, a maximum output power of 1.64 W was obtained at 1999.9 nm under 4.56 W of incident pump power, corresponding to a slope efficiency of 50% with respect to the incident pump power. To the best of our knowledge, this is the highest slope efficiency achieved for 2000 nm Tm:YAG lasers so far.
