Infrared supercontinuum from a large mode-area photonic-crystal fiber (PCF) for varied fiber lengths, powers and in dependence on the fiber mode structure under the 15 picosecond pulse excitation at the 1.08 μm pump wavelength with the coupled powers up to the PCF damage threshold are studied both experimentally and numerically. The conversion efficiency into a spectrum ranging up to 1.9 μm reaches 33%. The four-wave mixing is found to be dominating mechanism forming the supercontinuum structure. It is shown, that the supercontinuum bandwidth cannot be increased by only growth of the propagation length because there exists the optimum one. The analysis of inter-mode cross-modulation effecting supercontinuum smoothness, bandwidth and its temporal characteristics is presented.
