ABSTRACT:
A dual-cavity single longitudinal mode (SLM) laser oscillator generates a pulsed laser signal having a long pulsewidth, long coherence length, and good shot-to-shot energy stability. The laser oscillator has a first cavity between an output coupler and a rear mirror and a second cavity between the output coupler and an intra-cavity mirror disposed between the output coupler and rear mirror. High-loss cavity optics and a passive Q-switch achieve a very high number of round trips that reduce the number of cavity modes down to two or three. The dual cavity design further discriminates between the remaining modes and allows SLM operation. The laser oscillator and an amplifier can be used as a pump laser for a laser system that generates red, green, and blue pulses for holographic recording. A wavelength conversion stage uses optical parametric amplifier(s), doubling crystals, and sum-frequency mixers to produce RGB light from the pump pulses.
