Abstract

A compact diode-pumped Er, Yb:phosphate glass laser was developed for applications in eye- safe distance ranging and remote sensing. Under conduction cooling condition of laser diode arrays and laser active medium, the glass laser has the output pulse energy of 107 mJ at 5 Hz, and 80 mJ at 10 Hz, which correspond to optical-to-optical conversion efficiencies of 7.6% and 5.8%, respectively.
