Over 40-watt diffraction-limited Q-switched output from neodymium-doped YAG ceramic bounce amplifiers.

ABSTRACT

High power operation of high repetition Q-switched ceramic NdYAG laser is demonstrated using a master-oscillator power amplifier with a transversely-pumped bounce geometry. The laser system produced >40W high spatial quality output (M(2) <1.3) at a pulse repetition frequency of >100kHz. Pulse width of 35-80ns was achieved in 10-150 kHz pulse repetition frequency range of 10-150kHz.
