This work shows experimental evidence for a new quantum evaporation effect theoretically discovered by Bardou and Boosdt. In this effect the tunnelling probability of a particle through a barrier strongly increases when a small momentum is transferred to the particle during its reflection on the barrier. In our experiment we studied the induced tunnelling of a short optical pulse on a Newton-type optical barrier.
