Tip: Although the use of QQ will allow us freedom of the interception of any part of the screen picture, but the following two screenshots with the way the outcome will be better: If you want to interception of the entire screen you can use Print Screen key, the interception of a window is selected the window by pressing "Alt + Print Screen" key on OK.

提示：虽然QQ的这一用法可以让我们自由截取屏幕任意部分的画面，不过配合下面两种截屏方式效果会更好些：如果要截取全屏幕大家可以采用Print Screen键，截取某窗口则选中该窗口后按下"Alt+Print Screen"键就OK了。

The research work presented in this dissertation focused on developing the scheme and techniques of OPCPA. This dissertation gives the results of the theoretical and experimental investigation on OPCPA scheme. The validation of OPCPA at high energy level was demonstrated successfully. And some important results were achieved. Several key techniques related to developing table-top ultra-intense and ultra-short OPCPA laser system were put forward, for example, the generation of femtosecond seeding pulses, the precisely temporal synchronization of the pump and signal pulses, the pulse stretching and recompression, the OPCPA process with high energy conversion efficiency and etc. Based on the integration of these key techniques, a 1.46-TW/153-fs OPCPA table-top ultra-intense and ultra-high laser system has been developed, which, to the best of our knowledge, has generated laser pulses with the shortest pulse duration and the highest peak power among the joule level OPCPA systems in the world.
