Based on the experiment platform with ultra-wide spectrum pulse source of GW level, the thesis investigates the influence on the delay time and jitter of laser-triggered switch of some relative parameters, such as laser pulse energy, laser wavelength, working voltage, and focal length of lens. The experimental results show that, the delay time of the switch decreases gradually as the laser energy or the working voltage increases. When 266 nm laser is adopted, smaller jitter can be achieved than using 1 064 nm laser. On condition of high pressure and small switch gap, the use of lens with smaller focal length shortens the delay time. The jitter is less than 0.3 ns while the self-breakdown voltage is 220 kV, the working ratio is larger than 80% and the energy of the 266 nm laser pulse is 7 mJ. In this condition, the synchronization experiment of two GW-level pulse sources is carried out and the synchronization difference is below 0.3 ns at the probability of 85%.
