摘要: 光学角多路系统是主振功放(MOPA)装置的重要组成部分。它不仅连接着主振荡器、预放大器及主放大器三个KrF激光系统，而且起着压缩激光脉宽的作用。光学角多路能使主振激光脉冲在能量上得到足够的放大，并使泵浦预放、主放激光腔的电子束能量及其脉宽得到充分的利用。介绍了天光一号装置上MOPA光学角多路系统的结构,并结合多年来运行的实践，提出了若干优化措施。Abstract: The angular multipexing system is the chief part in the MOPA. It links the mainoscillator, preamplifier and main amplifier up together, and acts as a laser pulse wide compressor. The angular multipexing system can make full use of the electron energy in the cavity of preamplifier and main amplifier and the electron pulse width to amplify mainoscillator laser pulse in order to improve the power density on the target.The configuration of the angular multipexing system of the MOPA used in HeavenI is introduced in this article. Some advices are given to make an optimization based on the its performance in these year．
