Paper Abstract

In this work, resonant diode pumping has been demonstrated for Q-switched and CW Er:YAG solid state lasers (SSLs) at eye-safe wavelengths. Resonant pumping was realized by using high spectral brightness 1470 nm laser diodes. An efficient 1645 nm CW laser with output power >5 W in the TEM00 mode was demonstrated. Total optical-to-optical efficiency was >19%. More than 11 mJ of output pulse energy and an output peak power of ~400 kW have been achieved in the TEM00 mode for Q-switched operation.
