1. An apparatus, comprising:
- a laser source operable to generate a laser beam having a flux that exceeds a predetermined value;
an optical train operable to modify the beam such that the flux of the beam through a predetermined aperture does not exceed the predetermined value;
wherein the optical train comprises a beam splitting element operable to split the laser beam into two or more sets of beams having angle between any two sets of beams.

Abstract
An apparatus and method for modifying the spread of a laser beam. The apparatus comprises a laser source operable to generate a laser beam having a flux that exceeds a predetermined value and an optical train operable to modify the beam such that the flux of the beam through a predetermined aperture does not exceed the predetermined value. The optical train may include a focusing lens, a diffractive focusing vortex lens, a beam splitting device, or a two-dimensional diffraction grating.
