Laser Initiation and Radiofrequency Sustainment of Seeded Air Plasmas

Abstract

We have carried out research on high density [10(exp 11) - 4 x 10(exp 13)], large volume (500-2500 cc), high-pressure (20-760 Torr), laser initiated plasma produced in nitrogen, argon and air. The low ionization energy organic gas (TMAE) laser-initiated see plasmas create an initial condition that is used for plasma sustainment at much lower radiofrequency (RF) power levels (0.4 - 3 W/cc) than is the case for RF initiation alone.
