A photoelectronic trigger module with low time jitter and fast rise time is presented which is used to reduce the influence of electrical interference on trigger signal in the high-power laser system. It is made up of a transmitter and a receiver which are connected with each other by an optical fiber. Since the trigger signal is transmitted from the transmitter to the receiver in the form of light, it will not be affected by electrical interference during its transmission. This photoelectronic trigger module is able to provide an electrical pulse with amplitude of 4 V whose rise time is 4.8 ns. The peak-to-peak value of additional time jitter of trigger signal resulting from this trigger module is 317 ps which meets the requirements of high-power laser systems.
