Abstract
We extended the study of a diffractive laser beam shaping system which is originally designed for continuous waves (SPIE vol. 2863, pp 237-45, 1996). The beam profile of an ultra-short laser pulse passing through this optical system is calculated. Two different numerical methods, Monte Carlo and Gaussian method, are applied to this problem. We find that the Gaussian method yields better results because the step size algorithms used in this method are well suited for this specific problem. The Gaussian numerical simulation shows that the fluence still yields a top-hat radial distribution. Beam shaping of ultra-short laser pulses using this optical scheme is feasible.
