Fano profiles in two-photon photoassociation spectra

M. Portier, Michèle Leduc, Claude N. Cohen-Tannoudji

In this article we derive the lineshapes observed in two-photon photoassociation spectrocopy of molecules using an effective Hamiltonian adapted from previous work in atomic physics. The lineshape is decomposed in terms of sums and products of Breit-Wigner and Fano profiles, which we associate with physical absorption and emission processes, and to quantum interferences between transition amplitudes. We emphasize the specific features which do not exist in the atomic case, linked to the dissociation width of the photoassociated molecules in the electronic ground state.

Feshbach resonance-induced Fano interference in photoassociation

Bimalendu Deb, G. S. Agarwal

We consider photoassociation from a state of two free atoms when the continuum state is close to a magnetic field-induced Feshbach resonance and analyse Fano interference in photoassociation. We show that the minimum in photoassociation profiles characterized by the Fano asymmetry parameter q is independent of laser intensity, while the maximum explicitly depends on laser intensity. We further discuss the possibility of the nonlinear Fano effect in photoassociation near a Feshbach resonance.
