Laser and Radiofrequency Air Plasma Sources
Abstract
We have made substantial progress in producing laser initiated seeded organic gas plasmas in air with densities of 1x10 13/cc of 500 cc volumes with low temperatures of 0.3 eV. We have measured plasma density decay rates and been successful in radiofrequency sustainment of the laser-produced plasmas with reduced power levels compared to radiofrequency ionization alone. The laser-produced plasmas provide a load for the radiofrequency coupled power through the antenna that greatly enhances power coupling efficiency to the plasma. It greatly reduces the reflected power from the antenna-plasma load and suppresses transient processes that reduce the available radiofrequency power that can be coupled tot he plasma.
