Abstract
A method of accomplishing high-speed intensity variation of a polarized output laser beam includes securing an angle of light incidence sensitive optical element to a galvanometer system that provides high-speed transitioning of the angle of light incidence sensitive optical element between different angular positions. The high-speed transitioning provided by the galvanometer system varies an angle of incidence between an input laser beam and the angle of light incidence sensitive optical element to thereby provide high-speed variation of an intensity of a polarized output laser beam produced by the angle of light incidence sensitive optical element.
