An illuminator comprising a short-wave infrared (SWIR) laser, a fiber optic, and a lens optic. The fiber optic is coupled to the SWIR laser for mixing the modes of a beam emitted by the SWIR laser. The lens optic is coupled to the fiber optic for shaping the beam into a top-hat beam profile. A method for creating SWIR illumination includes emitting a laser beam with multiple modes from a SWIR laser, transmitting the laser beam through a multi-mode fiber optic, and transmitting the laser beam through a lens optic. Transmitting the laser beam through the multi-mode fiber optic can including mixing modes of the laser beam thereby reducing speckle and constructive and destructive interference in the laser beam. Transmitting the laser beam through the lens optic can include generating a top-hat beam profile.
