Based on diffraction integral formula and selfreproducing principle,diffraction integral equation for transverse modes in a circular symmetric resonator with an aperture diaphragm was disintegrated to finitesum matrix equation,and field distributions of transverse modes in the resonator were calculated by solving matrix for eigenvalues and eigenvectors.
结果证明,孔径光阑的位置和尺寸直接影响激光输出模式和花样。
6) aperture
[英]['æpətʃə(r)] [美]['æpɚtʃɚ]
孔径光阑
1.
According to the basic relation E =φ/A, a direct optical method for aperture area measurement was provided, based on known constant irradiance over the aperture.
根据辐射照度与面积的基本关系,采用平行等间隔的相同激光束相互重叠,形成空间均匀的照度区域,且覆盖孔径光阑。
补充资料:T制光圈
T制光圈(T number),又称T值。普通镜头的光圈是用F值表示的,但除了焦距和镜头口径之外,指将镜头的透过系数考虑在内的数值。
