针对参考时钟源高电平脉冲宽度窄(小于2?ns)和本底噪声大的问题，通过使用一种时钟低抖动整形技术方案，使参考时钟经过锁相整形后高电平脉冲宽度大于3?ns、锁相相位时间抖动均方根(RMS)值小于5?ps。目前该方案已成功用于星光III激光装置的联机实验，情况良好，对其他类似需要精密时钟的装置具有极大的借鉴意义。

The SG-Ⅲ laser facility (SG-Ⅲ) is the largest laser driver for inertial confinement fusion (ICF) researches in China, which has 48 beamlines and can deliver 180 kJ ultraviolet laser energy in 3 ns. In order to meet the requirements of precise physics experiments, some new functionalities need to be added to SG-Ⅲ and some intrinsic laser performances need upgrade. So at the end of SG-Ⅲ's engineering construction, the 2-year laser performance upgrade project started. This paper will introduce the newly added functionalities and the latest laser performance of SG-Ⅲ. With these function extensions and performance upgrade, SG-Ⅲ is now fully prepared for precise ICF experiments and solidly paves the way towards fusion ignition.
