Phase-conjugate emission of a two-mirror solid state laser

2002

We show that phase conjugation strongly contributes to the emission of a solid state laser in a two-mirror (Fabry-Perot) resonator , enabling dynamic correction of thermal lensing . Full correction of thermal effects is reached by vector phase conjugation .

Flashlamp-pumped Nd:KGW laser in MOPA configuration: comparative study of several rods

1999

The laser performance of the Nd:KGW crystal has been studied in a master oscillator and power amplifier configuration (MOPA). Several crystals from two different producers were investigated for the oscillator and the amplifier. A maximum single-pass gain of 25 was observed in free-running and Q-switched 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.
