Abstract
An uniquely high conversion efficiency of fundamental radiation from a Ti:sapphire laser to a supercontinuum is achieved through filamentary propagation in sulfur hexafluoride () to generate a uniform over-octave spectrum. Two different parts of the supercontinuum, firstly around the fundamental wavelength of and secondly within the newly generated frequency range around , are shown to be compressible down to minimal pulse duration of about demonstrating a potential of the method for single-cycle pulses generation.
