Abstract
In various embodiments, wavelength beam combining laser systems incorporate optical fibers and partially reflective output couplers or partially reflective interfaces or surfaces utilized to establish external lasing cavities.
Claims24
A laser system comprising:
- an array of beam emitters each emitting a beam;
- focusing optics for focusing the beams toward a dispersive element;
- a dispersive element for receiving and dispersing the focused beams, thereby forming a multi-wavelength beam;
- an optical fiber for receiving the multi-wavelength beam;
- and
- disposed within the optical fiber, a fiber Bragg grating for receiving the multi-wavelength beam, reflecting a first portion thereof back toward the dispersive element, and transmitting a second portion thereof as an output beam composed of multiple wavelengths,
- wherein a portion of the optical fiber is disposed within an external lasing cavity established between the array of beam emitters and the fiber Bragg grating.
