| Abstract: | The numerical analysis of CW multimode laser beam transformed by time-varying random phase plate is presented in this paper. The method is based on diffraction integral formula. The dependence of the intensity distribution on the element size, changing frequency and duty ratio is discussed in detail. The numerical results account for the experimental results satisfactorily. |
