Random noise processing using photon echo

摘要

The excitation of stimulated echo by two pulses of Gaussian white noise, which are originated from a single source and short coherent pulse is considered. The present work studies the nonlinear properties of average amplitude of the echo as function of the spectral power density. The mean value of the complex envelope of the echo is obtained by solving stochastic Bloch equations in Stratonovich sense. The results can be used for analysis of nonlinear excitation characteristics based on saturation effect in photon and spin processors.
