Abstract

The fluorescence spectrum of Yb:YAG crystal is analyzed and its gain characteristics are discussed. A regenerative amplifier is built, which works under a low temperature. The gain material is Yb:YAG crystal with the doping concentration of 8% back-end pumped by a laser diode. Through a signal pulse injection, we can get a 10.3 mJ laser pulse output with the repetition rate of 10 Hz and the pulse width of 10 ns at -90 ℃, and the magnification exceeds 107.
