This paper is to describe the precision delay pulse generator and digital delay pulse generator which will be used in the prototype of laser system. There are four independent delay channels output and a standard timing pulse output from the precision delay pulse generator, the delay resolution is 10ps, delay range is 200ns, the trigger jitter is less than 10ps. There are four independent delay channels output and a standard timing pulse output from the digital delay pulse generator, the delay resolution is 5ps, delay range is 10ms, the trigger jitter is less than 200ps.
