Based on diffraction integral formula and selfreproducing principle,diffraction integral equation for transverse modes in a circular symmetric resonator with an aperture diaphragm was disintegrated to finitesum 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。

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。
