The circuit is simulated with PSPICE program, and the results indicate that the designed circuit could generate kilo-voltage nanosecond pulse control signal that can match the applications requirement of electro-holographic optical switch well.

利用PSPICE软件对电路进行了仿真，结果显示，利用所设计的电路可产生千伏级的纳秒脉冲控制信号，能较好的满足电控全息光开关的控制需求。

The device consists of pulse control circuit, optical coupling isolation, MOSFET driver, waveform control unit, pulse voltage regulator modules, those are implemented based on CPLD and MOSFET.

以CPLD、MOSFET等为主要芯片设计了脉冲控制电路、光耦隔离和MOSFET驱动电路、波形调节单元、脉冲电压调节单元等，获得了符合加工要求的输出脉冲波形。

When the exterior circuit was certain, the output voltage was mainly determined by the biased, but it was also affected by the chip materials, the gap length on the device resistance and the optical pulse energy to a certain extent.

光电导开关输出电压的大小在外电路一定的条件下主要由偏置电压决定，同时开关芯片材料、开关电极间隙宽度以及触发光脉冲能量也会对其产生一定的影响。
