Controllable splitting method for high current pulse and apparatus therefor

A controllable splitting method for a current pulse, comprising the steps of:

• (1) electrically connecting a photoconductive switch between an input end and an output end of a current pulse circuit for the current pulse;
• (2) connecting a time-domain signal of the current pulse that is input to an external triggering port of a pulse laser to serve as an external trigger signal;
• (3) irradiating a laser pulse emitted by the pulse laser to the photoconductive switch;
• (4) when no current pulse is input at the input end, the pulse laser failing to receive the external trigger signal, and to output the laser pulse, the photoconductive switch being in an off state without the irradiation of the laser pulse, and no current being output from the output end;
• (5) when the current pulse is input at the input end, the time-domain signal triggering the pulse laser so that the pulse laser synchronously outputs a laser pulse on a time domain, the laser pulse irradiating the photoconductive switch so that the photoconductive switch is in an on state and an output current pulse with an output current pulse signal is output from the output end;
• (6) controlling the waveform of the current pulse by parameters of the photoconductive switch so that a current pulse signal having a split waveform is formed at the output end in synchronization with the time domain of the input end.
