Fiber-based output couplers for wavelength beam combining laser systems

摘要

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.

主权项

1. A laser system comprising:
an array of beam emitters each emitting a beam; focusing optics for focusing the beams toward a dispersive element; the 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 or on the optical fiber, a partially reflective interface 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.
