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.
当有其他物体遮挡在焦点前，入射激光的功率密度小于SBS的阈值，SBS不能发生。
The angle between the two branches is unchanged under the condition of the same phase jump and different incident intensity.
相同相位跃变、不同光强的光束分开角度基本保持不变。
Based on Kogelnik diffraction efficiency equation, the relation between the optimal incident intensity ratio and the writing angles is analyzed.
基于衍射效率公式，分析最佳衍射效率时入射光强比和写入角之间的关系。
