Abstract
The influence of the structure of holey-fibre cladding on the effective wav eguide mode area and the spectral broadening of femtosecond pulses of titan ium-sapphire and forsterite lasers is experimentally studied. These experim ents demonstrate that the increase in the air-filling fraction of the holey -fibre cladding may substantially enhance the spectral broadening of laser pulses due to the increase in the degree of light localisation in the fibre core.
