Paper Abstract

The paper describes the results of spectroscopic and generation investigations of SELG glasses with different concentrations of dopants for high-average power diode-pumped eye-safe microchip lasers. Transmission spectra of the laser glasses was measured and absorption coefficient calculated. The generation was carried out in two regimes: cw and quasi-cw. Up to 150mW of output power with slop efficiency 16% was achieved for cw generation and up to 300 mW of peak power with slop efficiency 19,4% for quasi-cw generation and duty-cycle 50%.
