Coherence of both self-frequency shifted solitons and short-wavelength non-soliton radiation generated in a micro-structure fibre was investigated experimentally for the first time. Their spectral, temporal and polarization characteristics were studied as well. We found the solitons generated in 30-cm-long fibre pumped with 50-fs pulses at 795 nm and 835 nm from Ti:Sapphire oscillator to be coherent, whereas degree of coherence of blue-shifted radiation was amounted to 0.25–0.57 depending on wavelength.
