Abstract—Room temperature, multi-wavelength operation in 0.3% doped Er:YAG laser with double etalons
pumped by a MgO:PPLN laser locked at 1532 nm was reported. Lasing occurred predominantly at 1645.1nm
and 1617.2 nm. 350 mW of 1645.1 nm, 160 mW of 1617.2 nm output were achieved under total incident pump
power of 7 W.
