Study of VUV Generation by Coherent Resonant Frequency Mixing in Metal Vapors.

Abstract

The properties of multiphoton resonances (two, four or more) are exploited to enhance up-frequency conversion rates. Simultaneously, the property of reversibility of coherent interaction is used to minimize the resonant losses (two-photon, four photon absorption). A source of tunable, near bandwidth limited pulses, of more than a millijoule energy per pulse has been developed. A new scheme of computer controlled data acquisition system made it possible to analyse, for the first time, the temporal coherence properties of the amplified pulses (at a rate of 20 pps). The method of interferometric autocorrelation has been applied to the study of multiphoton coherences. Two photon transmission measurements were performed through a heat pipe containing lithium vapor. (Author)
