Abstract

Two-photon optogalvanic spectroscopy of noble-gas-filled hollow cathode discharges is used to measure the bandwidth and absolute wavelength of a narrowband pulsed dye laser in the 580–610-nm range. The two-photon transitions can be made Doppler free and thus allow laser bandwidth and atom temperature effects to be distinguished. The results are illustrated with the prediction of the optimum conditions for an ultraviolet two-photon transition of singly ionized neon.
