Research on the High Accuracy Digital Delay Pulse Generator Using in the Ultra Short Laser Pulse Technology

Digital delay pulse generator is a high-accuracy and broad delay-scope digital synchronization system which is used to solve the large jitter problem of ultra short laser pulse output. The analog delay and digital delay are combined skillfully to satisfy the different requirements of delay time and the delay accuracy in all the critical points of each delay time periods.The generator provides one channel standard clock pulse output and four channel delay-pulse outputs ,the jitter of each output pulse is less than 500 ps. The output of the generator fits the requirement of the experiment very well.
