1,64 mkm Er:YAG laser resonantly pumped by a solid state Er:glass laser

Abstract

We report on theoretical and experimental studies of Er :YAG pulsed laser working in a quasi-three-level scheme. A numerical simulation of an optical multiple laser scheme is carried out. Electro-optically Q-switched operation of an Er:YAG laser at 1645 nm end-pumped by a laser Er-Yb phosphate glass is demonstrated. Pulse energies up to 3 mJ have been generated at a pulse repetition frequency of 10 Hz.
