We demonstrate a new method of generation of frequency-tunable megawatt femtosecond pulses in the infrared based on multisoliton supercontinuum generation in a large-mode-area photonic-crystal fibre (PCF) followed by the temporal compression of the PCF output. Photonic-crystal fibres with a core area of about 710 {mu}m{sup 2} are employed to convert microjoule femtosecond laser pulses with a spectrum centred at 1.39 {mu}m into pulses with a central wavelength of 1520 nm, a pulse width of 210 fs, and a peak power of about 1 MW.
