  • Patent number: 8036252
    Abstract: A mid-infrared system for optical probing is disclosed that comprises a mid-infrared fiber laser based on cascaded Raman wavelength shifting, a sample volume, and a detector or detection system. The cascaded Raman wavelength shifting process in optical fibers involves the emission of a plurality of optical phonons for at least some of the pump photonics involved in the process. As one example, using the cascaded Raman wavelength shifting process a pump laser wavelength between 1 and 2 ?m can be shifted down to between 2.5 to 10 ?m. In one embodiment, the mid-infrared fiber laser comprises a pump laser with a wavelength between 1 and 2 ?m, one or more stages of cascaded Raman oscillators implemented in fused silica fiber, and one or more stages of cascaded Raman oscillators implemented in mid-infrared fiber that transmits beyond 2 ?m.
