摘　　要：For linear electrooptic （EO） effect of femtosecond laser pulses that propagates along the direction of nonoptical axis in linear-chirped and periodically poled MgO：LiNbO3 （LCPPLMN）, we explore the compensation scheme for the phase mismatch and the group-velocity mismatch between the o- and e-light, and discuss the effect of the linear chirp parameter of the LCPPLMN on the waveform of the output o- and e-light. It is found that, for any input pulse duration, the phase mismatch and the group-velocity mismatch can be simultaneously compensated by the optimization of the linear chirp parameter. As a result, high conversion efficiency of linear EO effect can be performed. In addition, we discuss the influence of the linear chirp parameter on the temporal evolutions of the output o- and e-light pulse.For linear electrooptic （EO） effect of femtosecond laser pulses that propagates along the direction of nonoptical axis in linear-chirped and periodically poled MgO：LiNbO3 （LCPPLMN）, we explore the compensation scheme for the phase mismatch and the group-velocity mismatch between the o- and e-light, and discuss the effect of the linear chirp parameter of the LCPPLMN on the waveform of the output o- and e-light.
