Diagnostic Development for Study of In-Air Laser Induced Plasma

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 Nd:YAG 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.
