Pump-noise-induced Hanle effect in forward four-wave mixing

Abstract
This is an addendum to our previous publication [Phys. Rev. A 36, 143 (1987)] dealing with cross-correlationinduced resonances in four-wave mixing. The temporal fluctuations of the source lead to well-resolved Hanle resonances in forward four-wave mixing which is in contrast to the dephasing-induced resonance in the same geometry.
