Abstract
A compact single-frequency nanosecond green laser oscillator-amplifier system was developed. The single longitudinal mode oscillator consists in a cavity-coupled acousto-optically Q-switched Nd:YAG microlaser emitting pulses of 50 μJ energy, 10 nanosecond duration at 1064 nm wavelength. The oscillator pulses were amplified at 1-10 Hz repetition rate in a two-pass Nd:YAG amplifier up to 28 mJ energy. Infrared amplified radiation was frequency doubled (532 nm) in a KTP crystal with as much as 50% conversion efficiency. The pulsed green laser, with more than 1.5 m coherence length, was used as light source for the holography unit in the sensor of a multi-task device for nondestructive diagnosis in art conservation procedures.
