Abstract： We report the observation of bichromatic coherent population trapping under the transition 87RbFg =1 → Fe = 0 with two linearly polarized laser beams by means of a Hanle effect configuration. The mechanism behind this effect is identified, and numerical solutions for the pump rates equations are presented.
