The propagation approximation analytic expression and the propagation properties of hollow Gaussian beams(HGBs)through the annular aperture has been studied by using the method of compound Gaussian function.The effect of the output beam caused by different inter and outer radius of the annular aperture also has been analyzed.The results show that,the diffractive properties relative with the order of the HGBs,the width and inner radius of the diaphragm.
