Abstract
The changes in emission characteristics of a neon hollow cathode discharge by resonant laser excitation of 1s5→2p2 and 1s5→2p4 transition have been studied by simultaneously monitoring the optogalvanic effect and the laser induced fluorescence. It has been observed that resonant excitation causes substantial variation in the relative intensities of lines in the emission spectrum of neon discharge.
