In this Letter, we show that the fundamental pulsation frequency of the mode-locked laser can be multiplied by an integer number by simply changing the length of a secondary cavity formed by the AOM and an external mirror. Furthermore, we show that a mode-locked laser may be used to enhance the SNR in passive ring gyroscopes by matching multiple modes of the laser to those of the passive cavity.
