【摘要】 设计了一种基于MarxBankGenerator脉冲发生原理而设计的ns级上升沿调Q开关雪崩三极管高压脉冲发生器。它可以在20ns以内的时间在Nd:YAG激光器的电光调Q晶体(KD*P)两端加上1/4波高压,调Q时间由原来使用电子管时的90ns缩短为15ns以内,从而使输出脉冲的峰值功率由25mW增大至93mW,脉宽由16ns缩短为8ns。该调Q电路还具有体积小、功耗低、电磁辐射小、重复率高和工作寿命长等优点。更多还原

【Abstract】 A generator which can produce high voltage pulse with nanosecond rise time was designed.The generator is based on the use of avalanche transistor in a Marx Bank circuit.As a result,Qswitching speed increases from 90 ns to less than 20 ns,peak power of output pulse increases from 25 mW to 93 mW and pulse width decreases from 16 ns to 8 ns.The generator has many merits such as small bulk,low power consumption,low EMI,high repetition rate,long operating life etc.更多还原
