Paper Abstract

The results of spectroscopic and generation investigations of the concentrated Yb-Er laser glasses with different concentrations of dopants are presented. Absorption coefficient was calculated on the basis of measured transmission spectra of the laser glasses. Two regimes of the laser generation were investigated: cw and quasi-cw. Up to 180mW of output power with slop efficiency 18,5% for cw generation and up to 340 mW of peak power with slop efficiency 22 % for quasi-cw generation and duty-cycle 50% was achieved. The dependence of the output power on the temperature of the pumping diode and the active media were examined.
