针对铌酸锂晶体中飞秒激光脉冲线性电光效应, 研究了光学相位共轭 对群速度色散 以及一阶和二阶折射率色散的补偿方案. 结果发现, 在任意初始输入脉宽条件下, 这些色散基本上都能得到补偿, 输出脉冲波形基本上和输入脉冲相同. 在此方案中, 若同时在色散补偿铌酸锂晶体上对输出脉冲进行电光相位调制, 则在一定外加电场作用下, 输出脉冲的脉宽将进一步被压缩, 初始输入脉宽越小, 压缩程度越大.

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.-
