摘要

从理论上考虑了具有平坦波前的均匀单色光束在经过由方形锯齿孔径和空间滤波器组成的远地点后在远地点出口及其后的剖面变换。与圆形远地点几何形状的主要不同之处在于。分析了方形锯齿孔径角、菲涅耳衍射相位、孔径锯齿形状和锯齿高周期比的作用。

Laser beam shaping in an apodizer with a rectangular serrated aperture

Profile transformation of a uniform monochromatic beam with a flat wavefront after the propagation through an apodizer comprising a square serrated aperture and a spatial filter is theoretically considered at the apodizer exit and behind it. Main differences from the case of the circular apodizer geometry are shown. Roles of the square serrated aperture angles, the phase in Fresnel diffraction, the shape of the aperture serrations and serration height-to-period ratio are analyzed.
