Abstract
A laser source assembly (10) for providing an assembly output beam (12) includes a first MIR laser source (352A), a second MIR laser source (352B), and a beam combiner (244). The first MIR laser source (352A) emits a first MIR beam (356A) that is in the MIR range and the second MIR laser source (352B) emits a second MIR beam (356B) that is in the MIR range. Further, the beam combiner (244) spatially combines the first MIR beam (356A) and the second MIR beam (356B) to provide the assembly output beam (12). With this design, a plurality MIR laser sources (352A) (352B) can be packaged in a portable, common module, each of the MIR laser sources (352A) (352B) generates a narrow linewidth, accurately settable MIR beam (356A) (356B), and the MIR beams (356A) (356B) are combined to create a multiple watt assembly output beam (12) having the desired power. The beam combiner (244) can includes a combiner lens (364) and an output optical fiber (366). In this embodiment, the MIR beams (356A) (356B) are directed at the combiner lens (364) and the combiner lens (364) focuses the MIR beams (356A) (356B) onto a fiber facet (366A) of the output optical fiber (366). Moreover, the output optical fibe…
