Abstract
Using a high-intensity 1-ps laser we have demonsirated both second and third harmonic production in a jet of krypton gas. The production of even harmonics is a forbidden process in the dipole approximation. Both intensity and pressure scaling for the harmonic strengths were investigated. The laser was operated at 1.053-pin wavelength and l-ps pulse length resulting in intensities ranging from 1013 1016 W/cm2.
