Abstract
An apparatus and method for combining a plurality of laser beams to form a single output beam comprising employing a plurality of lasers and optically connecting an image rotator and recoupler to each of the plurality of lasers.
Claims16
An apparatus for phase locking a plurality of laser beams to form a plurality of phase-locked beams, said apparatus comprising:
- a plurality of lasers;
- and
- an image rotator and recoupler optically connected to each of the plurality of lasers, said image rotator and recoupler comprising an image rotator and a colinear input from said plurality of lasers and output to said plurality of lasers and wherein said plurality of lasers are phase-locked via self-seeding one of said plurality of lasers with another of said plurality of lasers.
A method for combining phase locking a plurality of laser beams to form a plurality of phase-locked beams, the method comprising the steps of:
- employing a plurality of lasers;
- optically connecting an image rotator and recoupler to each of the plurality of lasers, wherein the image rotator and recoupler comprise an image rotator and comprise a collinear input from the plurality of lasers and output to the plurality of lasers;
- self-seeding one of the plurality of lasers with another of the plurality of lasers;
- and
- phase-locking the plurality of lasers.
