title: Impulse-response function of photorefractive phase conjugation.
abstract: Explicit expressions for the impulse-response function of a photorefractive phase conjugator are derived. The expressions are in the form of an infinite series of Bessel functions. The results are derived by using the undepleted pump approximation and are therefore valid at least for small time intervals, even when the conjugator is unstable.
