You can use a cheap NPN transistor such as a 2n2222 to amplify this pulse, to interface with the next stage of electronics.
你可以使用一个便宜的npn型晶体管，比如2n2222，放大该脉冲到后续电子元件的接口。

An improved plan of silicon controlled rectifier (SCR) line type trigger is described in detail. Anew practical circuit of bipolar transistor trigger for high pulse repeat frequency is presented.
With the relay can be; but if you need to speed, you can use the transistor, FET and other switching elements to achieve PWM (pulse width modulation) speed.
