| Abstract: | In the practical application of laser,the beam shaping is often needed to better meet the actual needs,for this purpose,firstly the analytical formula for diffraction transformation of Gaussian beam through micro-circular aperture is derived from the Kirchhoff diffraction formula,then three kinds of shaping transformations of Gaussian beam through micro-circular aperture are analyzed and discussed,the three cases of shaping transformations of Gaussian beam through micro-circular aperture are simulated with ... |
