Abstract

A high-power Er:YAG laser that is in-band pumped by a high-power cladding-pumped erbium–ytterbium codoped fiber laser operating at 1532nm is reported. The Er:YAG laser produced 60.3W of continuous-wave output at 1645.3nm in a beam with M23 for 82W of incident pump power and 20W of TEM00 output with M2<1.2 for 32.4W of incident pump power. The slope efficiency with respect to incident pump power at pump powers of >20W was 81%. In the Q-switched mode of operation, a slightly modified resonator configuration incorporating an electro-optic Q switch produced pulses of 4mJ energy and 100ns (FWHM) duration, corresponding to a peak power of 42kW at a repetition rate of 1kHz for an incident pump power of 16.8W. The prospects for further improvement in continuous-wave and Q-switched performance are discussed.
