Phase matched third harmonic generation in sodium and rubidium vapor using both an inert gas and a second metal vapor for phasematching is demonstrated. Energy conversion efficiencies of 10 percent have been obtained and factors limiting conversion efficiencies are discussed. Theoretical analysis for a resonantly two-photon pumped frequency converter with application to the generation of tunable ultraviolet and vacuum ultraviolet radiation and also to infrared-to-visible up-conversion and imaging is presented. Calculations show that up-conversion power efficiencies in excess of 100 percent should be obtainable with tunable lasers having peak powers in the hundred watt to kilowatt range. Efficient up-conversion of low-level infrared radiation near 10 ..mu..m to the near ultraviolet employing resonant two-photon pumping of a non-allowed transition in sodium vapor is demonstrated.
