Abstract
The laser performance of the Nd:KGW crystal has been studied in a master os cillator and power amplifier configuration (MOPA). Several crystals from tw o different producers were investigated for the oscillator and the amplifie r. A maximum single-pass gain of 25 was observed in free-running and Q-swit ched mode. We obtained a maximum output amplified energy of 400 mJ at 30 Hz (with a pulse duration of 10 to 30 ns) with a divergence less than 3 mrad. We also studied the limitations of this configuration due to the very high gain of the Nd:KGW crystal.
