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.
