Abstract
In a laser generator for generating short high peak power pulses of lasant radiation, a mode-locked laser oscillator generator generates a train of short pulses to be amplified. The pulses to be amplified, as of 10 ps pulse width, are temporally spaced by the optical resonator round-trip time, i.e., six ns for a three meter long optical resonator. The pulses to be amplified are then injected into a moving slab Q-switched laser oscillator for seeding thereof and amplification therein. The temporal spacing of the injected pulses is matched to the round-trip time of the optical resonator of the moving slab laser oscillator for mode-locking the moving slab oscillator to efficiently achieve 100 dB of gain in the amplified pulses. The resultant amplified pulses have a peak power as of 500 MW. By chirping and broadening of the pulses to 300 ps before amplification, followed by pulse width compression in a grating pair, pecosecond pulses are generated of 150 GW peak power.
