A Study of the Characteristics of GaAs PCSS Time Jitter

GaAs光电导开关是超快激光器与光电半导体相结合形成的一类新型器件,在脉冲功率技术、精同步控制等领域有重要的应用价值。本文介绍了测量时间抖动的主流方法,归纳了触发激光脉冲特性以及外加偏置电压对不同工作模式下GaAs光电导开关时间抖动的影响,并在此基础上分析了时间抖动的产生原因,这为进一步研究开关时间抖动提供理论参考。

GaAs photoconductive switch (PCSS),a new type of device which combines uhrafast laser with photoelectric semiconductor,has been widely applied in fields of pulse power technology and precise synchronization control. This study briefly introduces the main measuring methods of time jitter,summarizes the characteristics of triggering laser pulse and the influence of extemal bias voltage on the time jitter of GaAs PCSS under different operating modes,and on this basis,analyzes the causes of time jitter,which can serve as theoretical references for further research on GaAs PCSS time jitter.
