SATURABLE ABSORPTION EFFECTS IN A XENON FLASHTUBE DISCHARGE

摘要

Plasma attenuation measurements have been made with YAG: Ndplus;3laser radiation traversing a 5hyphen;cm length of xenon plasma in a specially constructed flashtube. For low input signals, significant attentuation was observed with the attentuation persisting for several hundred microseconds following flashtube current cutoff. Experimental plasma transmission data were taken as a function of laser input power density. The results showed that there is a dependence on intensity of input radiation, i.e., the absorption tends to saturate as the laser input intensity increases.
