Abstract
High-order harmonic generation is observed in an argon jet using ellip tically polarized picosecond dye laser pulses. The experimental data a ppear to be in near agreement with the perturbation theory. However, t here is a general trend of small deviation from the theory. We specula te that such a deviation could be due to the laser induced coupling of upper states in or near the continuum which relaxes the selection rul es leading to an enhancement of harmonic emission.
