Abstract
,MOPA laser apparatus includes a master oscillator (22) and a preamplifier (24) providing a train of optical pulses. The pulse train is input to a fiber optic device arranged to multiply the pulse-repetition frequency (PRF) of the input pulse train. The PRF multiplying device (26) divides each pulse in the into train into two pulses and delays one pulse relative to the. other, some portion of one of the pulses and a portion of the other are delivered by the fiber optic PRF multiplying device as an output pulse- train, having a PRF equal to twice the PRF of the input pulse train.
