【摘要】 <正> 一、实验装置和原理 腔内剪切脉冲获得毫微秒脉冲系列的实验装置示于图1。M₁是全反射镜,M₂是部分反射（R=70％）镜。G是工作物质,工作物质为钕玻璃棒φ12×240毫米,两端磨斜2°。D是偏振元件,采用格兰棱镜,它只能透射偏振为P₁态的光。PC₁和PC₂是普克尔盒,PG₁采用KDP晶体,退压工作;PC₂采用KDP晶体,加压工作,加电压的时间7P由PC₂终端短路电缆严格确定。本实验To约6毫微秒。两块晶体都是圆柱形,环状电极。PC₁和PC₂退压和加压的开关都用光触发球隙。光触发球隙光源是通常的调Q激光器,球隙的上升时间大约为0.5毫微秒。两更多还原

【Abstract】 The method of selectively "pruning" the intraeavity signal is employed to produce a clipped pulse inside the cavity. The cavity subsequently behaves as a regenerative oscillator through amplification of this clipped pulse. Nanosecond pulse trains have been obtained with this technique.更多还原
