The theory and the experiment provide an ideal geometrical model for reducing the GVM between three waves, and provide a theoretical guidance and experimental verification for obtaining parametric pulses with higher gain and shorter duration in femtosecond optical parametric amplification.

该理论和实验研究为减小飞秒光参量放大中三波的群速失配提供了一个理想的几何模型，为获得高增益、窄脉冲宽度的参量光输出提供了理论依据和实验验证。

Moreover, the influence of the group velocity mismatch ( GVM) and group velocity dispersion ( GVD) on the filter for broad-bandwidth femtosecond pulse is analyzed.

同时还分析了群速失配以及色散对宽带飞秒脉冲双折射干涉滤波的影响。

The principle of the generalized vector method ( GVM) has been extended to the hexagonal crystal system material under the conditions of variable axial ratio and the mathematical model on it accordingly established.

将广义矢量法原理拓展到变轴比条件下的六方晶系材料，并建立了相应的数学模型。
