Abstract
A new method is suggested to transform a Gaussian laser beam to a Top-hat distribution using a kinoform. An iterative dummy area method is used to uniform the distribution in the top region of the Top-hat distribution for the design of the kinoform. Simulation results show that a plane-wave-neared Top-hat distribution can be obtained. In addition, the quality dependence of Top-hat distribution is also simulated on the relationship between the Gaussian radius and the size of the kinoform.
