The interaction region of the device is less than 20cm with the maximum waveguide radius of 3cm 它结构紧凑，整个器件作用区域小于20cm ，最大波导半径3cm 。
2.
A model made up of pulse compression grating pair with wavefront aberration is applied to calculate the effect of the wavefront aberration on pulse compression 理论分析结果表明：脉冲压缩光栅系统最大波像差不大于/ 4时，脉冲压缩比的最大变化率约为2 % 。
