| 摘 要： | 讨论了TW级飞秒激光放大装置中的同步时序系统原理,介绍了自行设计并建造的3套频率成分各异的TW级钛宝石飞秒激光放大装置,其中"极光Ⅱ"和"Titan"为两级放大系统,前者预放大与主放大重复频率均为10 Hz,后者采用1 kHz的预放大和10 Hz的主放大,"极光Ⅲ"为多级放大系统,预放大重复频率为10 Hz,主放大分别为1 Hz和15 min输出一发。针对各个放大装置的不同特点和对同步精度的具体要求,自行设计并建造了不同的同步时序控制系统,实现了各个激光放大系统的有效运转,同步精度达到200 ps。

| Abstract: | This paper presents fundamental theory on how to synchronize and control signals with different frequency in TW Ti:sapphire amplifier, and introduces three homemade TW laser systems with different repetition rate. Both Jiguang Ⅱ and Titan are two-stage amplifier, in former system, both pre-amplifier and main amplifier operate at same repetition rate of 10 Hz; in latter one, pre-amplifier operates at 1 kHz and main amplifier at 10 Hz repetition rate. Jiguang Ⅲ is multi-stage amplifier, in which pre-amplifier operates at 10 Hz, 1st-satge main amplifier 1 Hz and 2nd-stage one single shot every 15 min. The synchronization systems are specially designed for controlling above three TW laser systems, which enable these amplifiers working stably with synchronization precision up to 200 ps． |
