Observation and Relaxation of the Two-Photon Echo in Na Vapor

Observation and Relaxation of the Two-Photon Echo in Na Vapor

A pair of simultaneously pumped dye lasers has been used to produce in Na vapor the sum-frequency two-photon analog of the photon echo. Quantum-beat effects were observed. Using the effective elimination of Doppler broadening, the foreign-gas-induced relaxation behavior of the Na 3 2S1/2-4 2D3/2 sup...

Zusammenfassung:A pair of simultaneously pumped dye lasers has been used to produce in Na vapor the sum-frequency two-photon analog of the photon echo. Quantum-beat effects were observed. Using the effective elimination of Doppler broadening, the foreign-gas-induced relaxation behavior of the Na 3 2S1/2-4 2D3/2 superposition state was examined.
