摘要：
We numerically demonstrate the recovery of a message signal embedded in a chaotic carrier by using the chaotic masking method in microchip lasers. We found that for message recovery, the message component is required to be set at a frequency lower than the sustained relaxation oscillation frequency, because the difference in gain of the transfer function between chaotic and periodic components is large.
