    Abstract

    The recovery of a message signal embedded in a chaotic carrier using the chaotic masking method in microchip lasers was demonstrated. An acousto-optic modulator (AOM) was used to encode transmitted message components by modulating the intensity of the chaotic laser output. It was shown that a message can be extracted from the chaotic carrier at frequencies lower than the sustained relaxation oscillation frequency.
