Abstract:

This study aims to explore the feasibility of generating Radio Frequency RF signals with laser induced plasma LIP in air at atmospheric pressure. This report presents the development status of a suite of diagnostics meant to look for correlations between LIP properties and RF emission. The study aims to control the time dynamics and geometry of LIP to determine if those factors ultimately control RF output. Adjusting the time delay between an ultra-short-pulse-laser USPL 35 fs pulse duration and 6 mJ pulse energy and a NdYAG laser ns pulse duration and up to 700 mJ pulse energy allows control over the time dynamics. A spatial light modulator SLM provides control of the plasma geometry.
