Abstract

A method has been developed to characterise the fraction of laser energy transmitted through an initially over-dense plasma whilst accounting for broadening in the transmitted pulse spectrum. As such, this method accounts for the effect of self-phase modulation which may occur as an intense pulse propagates through beamline optics before being detected.
