| 摘 要： | 为了增加靶上的功率密度和耦合效率，基于饱和增益开关原理，发展了一种适用于放大自发辐射平滑光束的脉宽压缩方法。利用该方法，在赛格德大学的一台放电泵浦KrF准分子激光器上进行了实验，将该激光器输出的脉宽为14.5 ns的放大自发辐射光束压缩到了7.5 ns，并且保持了光束原有的均匀性。

| Abstract: | In order to increase the intensity on target and the coupling efficiency, based on optical gain switching theory the paper presents a method for shortening the amplified spontaneous emission(ASE) smooth pulses. The experiment has been performed on EMG-150, a discharge laser in the Department of Experimental Physics, University of Szeged. As a result, the pulse bandwidth is shortened to 7.5 ns from 14.5 ns, and the uniformity of the ASE beams is not affected. |
