Paper Abstract

We demonstrate Er:YAG laser operation at 1617nm with 6W output power and good beam quality (M-squared = 1.5) using a Volume Bragg Grating (VBG) as a wavelength selective output coupler. The low quantum defect operation of 5% is achieved by resonant pumping with a 1534nm fiber pump laser. The thermal loads of the crystal under 1617nm laser operation, under 1645nm laser operation, and under a no lasing condition are determined.
