Abstract

Raman heterodyne detection of rf-generated sublevel coherence is investigated in atomic samarium vapor under conditions of velocity-selective optical pumping. In the presence of rare-gas perturbers, velocity-changing collisions determine the characteristics of the rf-laser double-resonance signals by strongly affecting their linewidths and line shapes. The results can be quantitatively explained by a theoretical model that includes velocity-diffusion processes.
