Efficient frequency conversion of femtosecond pulses of a Cr:forsterite laser in tapered fibres is experimentally demonstrated. Unamplified 30-fs Cr:forsterite-laser pulses are used to generate the third harmonic in the phase-matching regime. Propagation of 75-fs, 10-200-nJ Cr:forsterite-laser pulses through a tapered fibre in the range of anomalous dispersion is accompanied by multiply phase-matched cascaded four-wave mixing, giving rise to a manifold of new spectral components in the visible range and substantial spectral broadening within the wavelength range from 1300 to 1600 nm.
