E-beam pumping KrF laser large caliber, high pump rate, can be directly used for ultrashort pulse laser amplification. The KrF laser was used to amplify the ultrashort pulse laser with the Terautron electron beam pump. The ultrashort pulse laser was amplified to 2 ~ 3J and 1.2 ps, and the laser power reached 2TW. The nonlinear absorption coefficient in quartz window mirrors and the pulse width of ultrashort pulse laser were measured
