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.
