Dependence of striation spacing in linear laser sparks on gas pressure and luminosity

  • 1. Sandia National Laboratories, Livermore, California 94550

Description

The variation of spacing between separate plasma regions in linear sparks produced by a laser spike train on initial gas pressure and the correlation between the spacing and plasma luminosity have been investigated for several gases in the range 20--760 Torr. Fourier analysis of the quasiperiodic images reveals details of these sparks not readily seen in the photographic and diode-array images
