For the linear electro-optic (EO) effect of ultrashort laser pulses in LiNbO3crystal, we investigate in this paper the compensation of the group-velocity dispersion, as well as the first- and second-order refractive dispersion by means of optical phase conjugation (OPC). It is found that for arbitrary input pulse durations, these dispersions can be compensated. And the waveforms of output pulses are almost the same as those of input ones. Also, the durations of output pulses can be compressed further when the phases of output pulses of OPC are modulated by EO effect in another LiNbO3for dispersion compensation. And the narrower the input duration, the more evident the compression of output duration becomes.
