Abstract
A simple holographic technique is used to generate a nondiverging hollow beam, which is similar to a Bessel beam. The hollow beam is obtained from a Gaussian beam with a high conversion efficiency (greater than 50%). We describe briefly the merit of this hollow beam, which has potential applications in particle collimation.
