Effects of radiative decay in four-wave-mixing spectroscopy: Narrow resonances produced by nonconservation of population, alignment, and orientation

P. R. Berman, Duncan G. Steel, G. Khitrova +1 more

We present experimental and theoretical results describing the presence of radiative-decay-induced narrow resonances in systems which do not conserve population, alignment, or orientation. We show how spectroscopic line-shape analysis of the nonlinear response can be used to determine all of the relaxation parameters characterizing a two-level atom.

Decay induced narrow resonances in backward nearly degenerate four-wave mixing spectroscopy

Jing Liu, J. T. Remillard, Duncan G. Steel

We present results showing narrow resonant behavior in a collisionless four-wave mixing interaction in atomic sodium. In a two-level system the excited state radiatively decays to the ground state at rate ${\ensuremath{\gamma}}_{\mathrm{sp}}$, and the two states decay to the reservoir at ${\ensuremath{\gamma}}_{1}$ and ${\ensuremath{\gamma}}_{2}$. If ${\ensuremath{\gamma}}_{1}$ and ${\ensuremath{\gamma}}_{2}$ equal the transit time, the resonance width is determined by the total decay rate out of state 2. In the presence of additional excited-state decay to another state, a narrow resonance with width ${\ensuremath{\gamma}}_{1}$ is oberved as a result of the effect of the additional excited-state decay on the magnitude of the ground-state probability amplitude.We present results showing narrow resonant behavior in a collisionless four-wave mixing interaction in atomic sodium.
