<p>A mid-infrared light source comprises a pump laser, a fiber stage, and a waveguide stage. The pump laser generates light having an input wavelength between approximately one to two microns . The fiber stage comprises one or more intermediate fibers, and shifts at least a portion of the input wavelength to an intermediate wavelength longer than the input wavelength. The waveguide stage comprises one or more mid-infrared waveguides, and shifts at least a portion of the intermediate wavelength to yield mid-infrared light. The mid-infrared light has a spectrum, where at least a portion of the spectrum is approximately two microns or longer.</p> |
