As for the study on the optical-wave technology in the cycle-time region, the following results have been achieved experimentally : (1) 4.1-fs, 1.78-optical-cycle pulse compression using a novel chirp-compensation technique based on a spatial light modulator (SLM), (2) the generation of 100-MHz repetitive, 7.1-fs transform-limited pulses by a new hybrid chirp compensation of a prism pair and a SLM for the glass-fiber output, (3) developments of a SH-FROG apparatus and a SPIDER apparatus which enable us to measure temporal intensity and phase profiles of 5.0-fs pulses and those of 5.0-fs pulses, respectively, and (4) the first demonstration of simultaneous, coherent three-color femtosecond pulse-shapings using a two-dimensional SLM and a spatial filter.

在周期时间域的光波技术研究方面，实验上取得了以下成果：（1）利用基于空间光调制器（SLM）的新型啁啾补偿技术实现了4.1 fs、1.78光周期的脉冲压缩;（2）产生了100 MHz的重复频率，7.1-fs的变换限制脉冲通过一个新的混合啁啾补偿的棱镜对和SLM的玻璃光纤输出，（3）研制了SH-FROG装置和SPIDER装置，使我们能够测量5.0-fs脉冲和5.0-fs脉冲的时间强度和相位分布。分别为fs脉冲，以及（4）使用二维SLM和空间滤波器首次演示同步、相干三色飞秒脉冲整形。
