Abstract
An efficient, compact diode-laser-pumped 2.94μm Er:YAG laser operating at 1.5 W continuous output power in a TEM00 beam with M2<1.2 has demonstrated pulsed operation in the quasi-cw regime with energies up to 9 mJ. Power scaling and output beam fiber-coupling at 85% efficiency in a hermetic package will be described.
