Abstract

Spectral performances of Yb:YAG crystal were studied. The optimal Yb3+ doping level in Yb:YAG crystal is 10at%, which is determined by the fluorescence lifetime measurement. It is shown that the cooperative up-conversion processes of Yb3+→Tm3+ energy transfer is responsible for the fluorescence quenching at high Yb3+ doping level. 300 mW of pulsed laser output power at 1030 nm was obtained by means of InGaAs LD pumped 20at% Yb:YAG crystal thin chip.
