General technology research on high precision synchronizing system for large-scale laser facilities

提出了一种用于大型激光装置的精密同步系统总体架构技术。该技术采用时钟及数据恢复、光级联技术成功地实现了多数量、多种类同步触发信号的有序组合,保证了同步触发信号的精度,获得的ps级精密同步触发信号的时间间隔抖动为:峰峰抖动小于100ps,均方根值小于10ps。

This paper introduces a general technology of high precision synchronizing system for large-scale laser facility. This technology realized the generation of magnitude number of multiple frequency synchronizing signals by adopting clock and da ta recover and optic fiber transmission. Time interval jitter of the picosecond precise signals was less than 100 ps （peak to peak jitter） and 10 ps （RMS jitter）. This technology was used on research of high precision synchronizing system for largescale laser facilities and good result was acquired. This technology can help building medical instruments and be used in related experimental tests.
