Abstract

Seventeen two-photon transitions for neon have been observed in the 580 - 635 nm spectral region for use in the spectroscopic study of its higher excited levels, which are not accessible by one-photon absorption. To compare the two and one-photon absorption signals being originated from the lower level, an effort was made to record single-photon optogalvanic spectrum in the available wavelength region. The dependence of the optogalvanic signal on the laser power has also been studied. The optogalvanic signals were obtained from a commercial neon-filled hollow-cathode lamp, which was irradiated with pulsed dye laser pumped with N₂ laser.
