Abstract
Disclosed are optical beam delivery devices and methods to modify an angular intensity distribution of an input beam so that it is converted to an output beam having an adjustable near-field transverse spatial intensity distribution. In some embodiments, adjustment of the angular intensity distribution is achieved by increasing an angular offset in response to controllable perturbation. In some other embodiments, adjustment of the angular intensity distribution is achieved by increasing an angular width (divergence) in response to controllable perturbation.
