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.
