We firstly bring forward and realize technologies of arbitrarily shaping laser pulse in the time domain by chirped pulse stacking, programmablely shaping spatial intensity by crystal liquid diaphragm, focused spot smoothing using angular spectrum dispersion by special gratings and detecting and compensating the small patch wave front aberration. Precise, programmable, efficient and \'all parameters\' condition of high power laser system has been obtained.

首次提出并实现了啁啾脉冲堆积型的时间波形任意整形；液晶光阀可编程光强空间整形；特殊光栅光谱角色散焦斑束平滑和小尺度波前畸变的探测和补偿，从而对高功率激光系统的激光束实现了高精度、可编程、有效的"全息"控制。

From the point of view of eliminating angular dispersion, the planar tilt errors and groove parallelism can ompensate each other, and the groove-width difference and planar errors of tip can also compensate each other.
