Abstract
A system and method for increasing efficiency and power output of a multi-wavelength beam combining system through providing a common output coupler to reflect feedback that stabilizes or individually seeds each emitter, and wherein the individual feedback is preserved by mitigating cross-coupling, wherein a multi-wavelength beam comprised of radiation having a plurality of wavelengths, high brightness and power.

15. A wavelength beam combining laser system comprising:
-
a plurality of beam emitters each emitting a beam; a dispersive element for receiving and dispersing the beams; a cross-coupling mitigation system for receiving and transmitting the dispersed beams while reducing cross-coupling thereof; and a partially reflecting output coupler positioned to receive the beams transmitted by the cross-coupling mitigation system, transmit a first portion thereof as a multi-wavelength output beam, and reflect a second portion thereof back toward the cross-coupling mitigation system, wherein the partially reflecting output coupler is disposed within a Rayleigh range of the beams transmitted by the cross-coupling mitigation system. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28)
