    Abstract: Apparatus and methods for generating controllable, narrow-band radiation at short wavelengths, driven by two colors injected into a structured waveguide. The use of multicolor excitation with the structured waveguide allows the use of very small guided beam diameters, without damaging the waveguide. Reduced guided wave mode area combined with low intensities required to drive wave-mixing frequency conversion allow the use of very compact, high average power, moderate peak intensity femtosecond fiber laser technology to drive useful conversion efficiency of laser light into the deep-UV and vacuum-UV at MHz repetition rates.
