Abstract

The beam divergence of high-order harmonics generated in Helium by an ultra-short Ti:sapphire laser (7 fs and 30 fs) is experimentally characterized by means of a flat-field, high-resolution spectrometer. The harmonic beam divergence is also analysed as a function of the gas-jet position relative to the laser beam waist. Results, which are partly different from previous measurements performed at longer laser pulse duration, are discussed
