✦ Synopsis

The central spot of COS beam (CS-COS) can be obtained from COS beam by using the zero ÿeld truncation technique. The transversal intensity distributions of CS-COS through three di erent kinds of aperture functions are simulated numerically from the near ÿeld to the far ÿeld. It is shown that the CS-COS has the property of eliminating the di raction fringes in the whole propagation process if a suitable aperture is introduced.
