Abstract

Nondegenerate four-wave mixing (NDFWM) in a double-Λ system of Rb atomic vapor was achieved for collinear pump fields. By comparison of different pump–probe configurations, direct experimental evidence of influence of coherent population trapping on the output power of the NDFWM signal was established. A maximal efficiency for generating the NDFWM signal exists for a moderate pump power in this double-Λ system.
