title: Doppleron-induced stimulated reflection.
abstract: In a gaseous system, energy can be transferred from an intense incoming beam to a counterpropagating probe beam at the same frequency. The effect may be interpreted in terms of Doppleron processes and arises because the medium undergoes interaction with beams of different effective frequencies owing to the Doppler effect.
