| Abstract: | On the basis of one-dimensional Bragg diffraction analyzing method, a 2-D intensity distribution of diffraction field is derived. The experimental results are given. The factors which inflnenoe the intensity distribniion of diffracted light spot are discussed. A new idea for designing the shape of diffracted light spot is proposed,, in which the diffraction efficiency, rise time and light spot shape are all considered. |
