Patent ID: 7724354

Claim:
A range finder system or target designator system comprising an optical system output; a pulsed diode master-oscillator/power-amplifier (MOPA) laser system, said laser system comprising a diode laser source having an optical output operationally connected to said optical system output and each of the following groups of features: a) said laser source being configured to operate in a pulsed manner by a source operating pulse signal and said power amplifier being configured to be pumped in a pulsed manner by a pump operating pulse signal, pulses of said source operating pulse signal and pulses of said pump operating pulse signal being synchronized in time; optical gain between an input signal to said power amplifier and an output signal from said power amplifier being adjusted by adjusting said pump operating pulsed signal; b) a fiber optical band-pass filter interconnected between said output of said laser source and said system output, said fiber optical band-pass filter having a pass-band characteristic, said characteristic being spectrally and automatically shifted matched with a spectral shift of a spectrum band of laser light subjected to filtering by said optical pass-band filter.
