The mode structure of supercontinuum emission generated by femtosecond pulses of Ti:sapphire laser radiation in microstructure fibres is studied. The long-wavelength (720 - 900 nm) and visible (400 - 600 nm) parts of supercontinuum are shown to be emitted in spectrally separable isolated spatial modes. These spectrally sliced single modes of supercontinuum emission possess a high spatial quality, verified by efficient nonlinear-optical frequency conversion. (control of laser radiation parameters)
