摘要: The photoassociation (PA) spectrum is analysed in the presence of a magnetic Feshbach resonance. A nonperturbative solution problem yields analytical expressions for PA linewidth and shift which are applicable arbitrary laser intensity field tuning We show that by close to Fano minimum, it possible suppress power broadening at increased intensities. This occurs due quantum interference transitions from unperturbed perturbed continuum. Line narrowing high intensities accompanied large spectral shifts. briefly discuss important consequences line cold collisions.
