Photonic-crystal fibers (PCFs) are widely recognized as efficient sources of white-light supercontinuum. Here, we show that a combination of an ultrashort-pulse ytterbium PCF laser with a highly nonlinear PCF enables all-fiber generation of ultrashort pulses of coherent UV radiation in the black-light spectral region with all the key processes, such as lasing, amplification, and conversion of the amplified PCF-laser output to the UV range, taking place in specifically designed fiber components.
