Phys. Rev. Lett. 98, 160201 (2007) [4 pages]Optimal Stochastic Enhancement of PhotoionizationReceived 28 November 2006; published 20 April 2007 The effect of noise on the nonlinear photoionization of an atom due to a femtosecond pulse is investigated in the framework of the stochastic Schrödinger equation. A modest amount of white noise results in an enhancement of the net ionization yield by several orders of magnitude, giving rise to a form of quantum stochastic resonance. We demonstrate that this effect is preserved if the white noise is replaced by broadband chaotic light. © 2007 The American Physical Society URL:
