One- and two-photon laser optogalvanic spectroscopy of neon in the 570–626 nm region

Eleven two-photon transitions originating from the 2p 53s[3/2] 2, 2p 53s′[1/2] o, 2p 53s[3/2] 1, and 2p 53s′[1/2] 1 states to the 2p 54d configuration states have been investigated in the optogalvanic spectrum of neon in the visible region (570–626 nm) for the first time. The two-photon assignments...

Description
Summary:Eleven two-photon transitions originating from the 2p 53s[3/2] 2, 2p 53s′[1/2] o, 2p 53s[3/2] 1, and 2p 53s′[1/2] 1 states to the 2p 54d configuration states have been investigated in the optogalvanic spectrum of neon in the visible region (570–626 nm) for the first time. The two-photon assignments are confirmed by evaluating the temporal evolution, power dependency, and line widths of the optogalvanic signals. The time evolution of the optogalvanic signals for the two-photon transition originating from the metastable 2p 53s[3/2] 2 state to the 2p 54d′[3/2] 2 state has also been studied at different discharge currents.
