Abstract
A pulsed laser system capable of producing pulses of radiation at relatively high peak power at a single resonator mode, said system comprising PA0 a master laser oscillator capable of producing a beam of radiation at a desired frequency to be introduced to a power laser, PA0 a radiation-responsive pulsed power laser oscillator including an optical resonator formed by a set of reflectors, said laser adapted to receive periodic application of a voltage pulse, said optical resonator arranged to receive said introduced beam at least during the periodic application of said voltage pulse to said power laser whereby the frequency of radiation emitted by said power laser can be determined by the frequency of said introduced beam, PA0 monitoring means acting between pulses of said power laser to optically monitor the resonator cavity of said power laser to determine the frequency of the resonator mode of said power laser and produce a signal dependent upon said frequency, PA0 and stabilizing means responsive to said signal of said monitoring means to maintain the center frequency of the mode of said power laser in close coincidence with the frequency of said master oscillator.
