中文摘要	为利用现有装备简单获得纳秒脉宽、峰值较高的单脉冲激光,满足军事应用和高温等离子体干涉研究的时间分辨要求,采用专利技术优化了调Q脉冲激光自斩波KDP泡克耳斯盒电光开关的触发狭隙,解决了19 kV全波电压下静态绝缘阻断和调Q激光脉冲前沿低阈值击穿双重可靠以及全系统动作同步,确保了触发的快捷和峰值附近斩波,实现了从传统红宝石激光器脉宽30 ns,能量80 mJ的调Q激光脉冲中斩出1.7 ns,4 mJ的单脉冲激光。实验和分析表明,预处理崎化了开关电极间的场分布,强化了激光触发作用,保证了斩出脉冲的窄脉宽和高峰值。; For obtaining simple mono-pulse laser of nanosecond burst-length and high peak power with available equipments in order to satisfy time-resolved demands in something to do with military application and in interferometric research of high temperature plasma,the trigged gap of KDP Pockels cell for chopping Q-beam itself was optimized by using certain patent technique,the dilemmas of dual reliability as well as synchronism of whole system were overcome in both static electric-separating of the gap enduring at full-wave voltage(Vλ) of 19 kV and easily puncturing of the insulating film between gap′s electrodes by the low front of Q-beam self-triggering,the high-speed triggering and the chopping near the peak of Q-beam were guaranteed,and a mono-pulse laser of 1.7 ns burst-length with 4 mJ pulse energy cut apart from Q-beam of a 30 ns/80 mJ traditional ruby laser was realized.Experimental investigation and theoretical analysis indicate,the optimized pre-processing distorted the distribution of the electric field between gap′s electrodes,strengthened the effect of the Q-beam′s triggering,and ensured the chopped laser pulse with short duration and high power.; 国家自然科学基金(10035030)资助项目
