Abstract

The laser optogalvanic (LOG) spectrum of Ne in the region 610–730 nm has been recorded using Nd-YAG laser pumped dye laser and a Hamamatsu FeNe hollow cathode lamp. Forty-five lines have been observed in the LOG spectrum and have been explained as originating from one- and two-photon transitions in Ne. The negative signal for a few lines and the observed variation in LOG signal with lamp voltage and laser power have been explained.
