Abstract
In embodiments, the present invention is directed to systems and methods for operating an incoherently beam combined (IBC) laser. The IBC laser may comprise an integrated set of emitters or a set of discrete emitters. Each emitter is associated with a high-pass, low-pass, or bandpass optical filter. The emitters and filters are disposed in an ordered arrangement thereby defining a common optical path. Near the end of the common optical path, a focusing lens may be utilized to focus the output beams from each of the emitters into a fiber. A partially reflective component may be embedded in the fiber to provide feedback to each of the emitters. By selecting the optical characteristics of the filters, light originating from a specific emitter is fed back to the same emitter and to no other emitter. Accordingly, multiple external laser cavities are created on the same optical path.
