Production of temporally apparent intensity distribution by rapid perturbation of variable beam characteristics optical fiber

摘要

Disclosed are an optical beam delivery device, systems, and methods for sequentially adjusting, with respect to members of a set of confinement regions, a propagation path for establishing a controllable, temporally apparent intensity distribution. The disclosed techniques entail applying to a variable beam characteristics (VBC) fiber different states perturbation to change the propagation path and the members of the set of confinement regions through which a confined portion of an adjusted optical beam propagates, thereby establishing at an output end of the VBC fiber the controllable, temporally apparent intensity distribution.
