Physical Sciences Inc. (PSI) has been awarded a research program from the U.S. Air Force to develop a compact quantum cascade laser (QCL) module that combines the outputs from seven high power mid-wave infrared QCLs using infrared fiber in a 7×1 fiber combiner configuration.
The module will feature a fiber taper section that adiabatically reduces the fiber core diameter in order to produce a beam with the required quality factor. The module output is fiber-coupled, which is particularly convenient for distributed aperture applications or whenever the laser and its associated thermal and electrical drive infrastructure must be located apart from the optical output head, typically for size, weight, and power (SWaP) considerations.
Both the midwave-infrared (MWIR) laser and fiber technology involved in this project bring associated advancements to medical and industry processing applications.
