Observation and relaxation of the two-photon-excited-state trilevel echo in sodium vapor
T. J. Chen, D. DeBeer, Sven R. Hartmann
The collisional relaxation cross section of the excited 3P‐3D superposition state of Na with Ar is measured. A photon echo from the 3P‐3D transition in Na vapor is spontaneously emitted at λ=8183 Å after excitation of the 3D state and for the 3P3/2 state. (AIP)
