A device for the generation of supercontinuum in infrared fiber with a pump light comprising a microchip laser operating with a wavelength of 1.0 μm or greater that can be wavelength shifted though a nonlinear element to a wavelength beyond the two-photon absorption of the infrared fiber and launched into infrared fiber whereby the spectrum is broadened in the infrared fiber through various nonlinear processes to generate a supercontinuum within the mid-IR from 2 to 14 μm.
