Abstract
By using a diffractive optical element (DOE), a new method to generate dark hollow laser beam (DHLB) is presented in this paper. The optimization theories to design the DOE can obtain a globally optimal solution in an exact analytic form. The generated DHLB shows good performances for actual applications, which testifies the validity of this new method.
