Influence of the 61 S 0a63 P 1 resonance on continuous Lyman-I- generation in mercury
Continuous coherent radiation in the vacuum ultraviolet at 122 nm (Lyman-I-) can be generated using sum-frequency mixing of three fundamental laser beams in mercury vapor. One of the fundamental beams is at 254 nm wavelength, which is close to the 61 S 0a63 P 1 resonance in mercury. Experiments have...

| Zusammenfassung: | Continuous coherent radiation in the vacuum ultraviolet at 122 nm (Lyman-I-) can be generated using sum-frequency mixing of three fundamental laser beams in mercury vapor. One of the fundamental beams is at 254 nm wavelength, which is close to the 61 S 0a63 P 1 resonance in mercury. Experiments have been performed to investigate the effect of this one-photon resonance on phase-matching, absorption and the nonlinear yield. The efficiency of continuous Lyman-I- generation has been improved by a factor of 4.5. |
