摘　　要：采用时间关联复测方法,用光电管结合数字示波器,利用高功率激光装置三倍频测量组件中的时间测量模块实现多路激光到达靶点时间同步的同发次测试。通过光束前端输出的任意波形发生器结合光纤放大传输组件中的光纤延迟器实现激光装置多束激光到达靶室时间同步精密调节,分析结果表明多束激光束间同步测量精度小于30ps,测试技术和方法为多路激光时间同步精密诊断提供技术支撑。Synchronization measurement of multi-beams for high power laser facility is achieved at the same time.The time correlation and duplicate measurement method,temporal profile diagnostic module of tripled frequency,and the high-speed digital oscillograph and transient photodiode are used.The synchronization adjustment is obtained by arbitrary wave generator and optical delay cell of front end.Results show that the errors of the synchronization measurement are less than 30 ps.The measurement technology and methods are important for synchronization measurement of multi-beam laser facility.
