Аннотация:
Four-wave mixing in atomic hydrogen with the generation of coherent Lyman- beta radiation at 102.6 nm was investigated experimentally and theoretically in the low density limit. We demonstrate that in this doubly-resonant system, the application of intense laser radiation to strongly couple the 2s and 3p levels causes transparency in the 3p from 1s transition, leading to reduced absorption of the generated Lyman- beta radiation, and to increased conversion efficiency.
