| Abstract: | Eleven two-photon transitions originating from the 2p53s3/2]2, 2p53s′1/2]o, 2p53s3/2]1, and 2p53s′1/2]1 states to the 2p54d 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 2p53s3/2]2 state to the 2p54d′3/2]2 state has also been studied at different discharge currents. |
