ABSTRACT:
A stable high gain laser includes a Q switched multiple axial mode high gain oscillator, an oscillator for generating a stable optical wave at a first frequency, the first frequency being within the band of the multiple modes of operation, and a coupler for injecting the stable optical wave into the high gain oscillator whereby the axial mode nearest to the frequency of the injected wave selects a single axial mode and through gain saturation suppresses other modes of the high gain oscillator.
