Abstract
The influence of the structure of holey-fiber cladding on the spectral broa dening of femtosecond laser pulses is experimentally studied. These experim ents demonstrate that the spectral broadening of 70-fs pulses of 800-nm Ti: sapphire laser radiation transmitted through 2- and 3- mum-pitch holey fibe rs can be enhanced by a factor of about 1.5 by increasing the air-filling f raction of the fiber cladding from 16 up to 65%.
