Abstract :
A laser beam propagating through the atmosphere and reflecting off a plane mirror is modelled by a stochastic bilinear system. The model consists of a random Schroedinger equation in which a white noise, representing the effects of turbulence, is multiplied by the state. The reflected beam is an anticipative random process, and cannot be represented in a straightforward way by an Ito integral. The author derives a white noise model, and discusses an approximation of product form type. The product form approximation is shown to converge to the product of two Ito integrals
