Abstract: Systems and methods for generating infrared radiation are provided. The systems and methods may generate, via one or more pump sources, one or more pump beams. The one or more pump beams may define a single beamline. The systems and methods may further generate, via a nonlinear optical converter, a first signal wavelength, a first idler wavelength, a second signal wavelength, and a second idler wavelength based, at least in part, on the one or more pump beams. The first signal wavelength and the first idler wavelength may be independently variable from the second signal wavelength and the second idler wavelength. The systems and methods may further output, via the nonlinear optical converter, a mid-wave infrared (MWIR) beam including three or more wavelengths in the single beamline.
