Abstract
The spectral properties of harmonic radiation generated in neon by laser pu lses with duration from 30 fs down to 5 fs have been investigated. In the 3 0-fs temporal regime we have achieved continuously tunable sub-20-nm radiat ion by changing the gas jet position relative to the laser beam waist. We s how that the results of a one-dimensional propagation code partially includ ing three-dimensional focusing effects an in good agreement with the experi mental results. Finally, we have performed a spectral characterization of h armonic radiation in the sub-10-fs temporal regime.
