3、By using this analytical method, propagation and transformation characteristics of light beams through an apertured ABCD optical systems are analyzed analytically.
4、Our calculations show that the Bessel-Gauss beam can be produced in the focused plane of the ring apertured Gaussian beam, this method is efficient and simple.
2、Two ABCD matrices for describing hard apertured Gaussian beams weakly diffracted in the far field are defined.
1、Propagation of a Lorentz beam through an apertured misaligned paraxial optical system
