Abstract
A MIR laser source that produces a fixed frequency output beam that is within the MIR range includes a QC gain media, and a wavelength dependent (“WD') feedback assembly that is spaced apart from the QC gain media and that cooperates with the QC gain media to form an external cavity. The WD feedback assembly may be used to precisely tune and control a lasing wavelength of the external cavity, and the position of the WD feedback assembly relative to the QC gain media may be fixed to maintain the precise lasing wavelength of the external cavity. With this design, each MIR laser source can be individually tuned to achieve the desired fixed frequency output beam that is within the MIR range.
