Abstract

A photon echo from the allowed 3D–3P transition in Na vapor is spontaneously emitted after a single-pulse one-photon excitation of the 3P state is followed by a single-pulse two-photon excitation of the 3D state. The collisional relaxation cross section of the excited 3D–3P superposition state of Na in Ar is measured.
