摘　　要：由多通放大器的理论计算了脉冲的放大特性，并进行了钛宝石的四程放大实验。当输入信号光为１ｍＪ时，通过四程放大，获得Ｔ２０ｍＪ的脉冲输出。Although regenerative amplifier is one of the most used preamplifiers, a number of electro-optical elements are necessary for trapping and dumping the weak signal pulse, which limits the outputenergy. Based on the basic theory, the gain characteristics of the multi-pass amplifier is analyzed. A fourpass scheme is employed to carry out the multi-pass experiments which successfully yield 20mJ output energy.
