Abstract:
1. A stabilized laser system comprising: a plurality of n lasers, each of which, while emitting light and having a preselected portion thereof fed back thereto, causes the fed back portion to be amplified and shifted in wavelength in a first direction which is spaced apart from a center wavelength of the feedback signal; a feedback stabilization arrangement coupled to the plurality of n lasers for generating a feedback signal having a wavelength spectrum peaking at a wavelength shifted in an opposite direction to the first direction generated by plurality of n lasers in response to the feedback signal so as to provide an output signal at the output of the stabilized laser system having a wavelength spectrum that peaks essentially at a desired wavelength; and a reflector located at a predetermined signal roundtrip time delay distance from the feedback stabilization arrangement for receiving the output signal therefrom, for passing a first portion thereof therethrough, and for reflecting a remaining second portion thereof back to the feedback stabilization arrangement as a secondary feedback signal that contributes to each of the plurality of n laser sources being set in a stable coherence collapse mode.
