Abstract

The third harmonic emitted into a narrow, hollow cone pointing in the direction of laser propagation was experimentally studied. In this study, a Ti:sapphire-Nd:glass laser system was used. A new theory that describes how phase matching in a plasma can result, was developed to explain the results. The signal level of the harmonic for a circularly polarized pump pulse was found to be on the same order of magnitude as that for a linearly polarized pump pulse.
