Stimulated radiative recombination has been demonstrated experimentally in and collisions using a merged electron - ion beams apparatus with field ionization detection of the excited neutral products. Enhancement of the recombination over spontaneous recombination to form the n=11, 12 and 13 levels of atomic hydrogen and the n = 11 and 12 levels of atomic helium by factors of between 1000 and 3000 have been found using a laser power of 8 W. Evidence for the resolution of fine-structure levels has been seen for the case of helium.

Stimulated electron-ion (-atom) recombination at a resonance

A. Lami, N. K. Rahman, Farhad H. M. Faisal

The problem of stimulated recombination at a resonance is investigated by a time-dependent, non-perturbative approach. The number of pairs recombined by a laser pulse is computed as a function of the intensity, of the pulse duration, and of the initial electron-energy distribution (as well as of the parameters which characterize the atomic resonance and its field-induced coupling to the final bound state). The role of spontaneous emission (or other paths) from the recombined state (if it is excited) is also discussed. Numerical results are given including an example of recombination to the ground state in the Sr atom.
