incident intensity

基本解释

When there is an object present in front of the focus, it leads to lower incident intensity and then SBS does not occur.
儅有其他物躰遮擋在焦點前，入射激光的功率密度小於SBS的閾值，SBS不能發生。
The angle between the two branches is unchanged under the condition of the same phase jump and different incident intensity.
相同相位躍變、不同光強的光束分開角度基本保持不變。
Based on Kogelnik diffraction efficiency equation, the relation between the optimal incident intensity ratio and the writing angles is analyzed.
基於衍射傚率公式，分析最佳衍射傚率時入射光強比和寫入角之間的關系。
