Research for the relation between small signal gain coef ficient and pump - energy density of high - power off - axis two - pass amplificati on 离轴高功率双程放大系统中小信号增益系数与泵浦能密度关系研究
The ger - kit assembly is made entirely of a sturdy black anodized aluminum ; the interior surfaces are bead - blasted to reduce off - axis reflections Kit组件完全由坚硬的黑色电镀铝制成。内表面为雾珠面以减少轴外反射。
In this , we focus on the phenomena of the induced focusing when two beams propagation in self - defocusing nonlinear media in an off - axis geometry 本论文旨在研究三维自散焦介质中由交叉相位调制效应诱导的光束聚焦。
We study the evolution of a probe beam profile in the influence of a pump beam in the off - axis geometry and obtain the typical process of probe focusing 详细研究了泵浦光束输入振幅对信号光束波形的影响，得到了三维自散焦介质中初始高斯信号光束聚焦时波形的典型演化过程。
This off - axis capability , as it is called , increases lethality and survivability by allowing the pilot to target threats with head instead of aircraft motions 这种离轴能力，就和它的名字一样，通过允许飞行员头部的运动而不是飞机的运动来瞄准威胁，增加了飞机的杀伤能力和生存能力。
