Abstract
Absorption of CO2 laser radiation is experimentally shown to be a useful plasma‐diagnostic technique, spatially, temporally, and quantitatively. Electron densities determined from absorption agree well with shock‐produced plasma values. Comparison of densities obtained via absorption, interferometry, and Langmuir probes in a plasma jet also show good agreement in magnitude and spatial dependence.This publication has 6 references indexed in Scilit:
