Abstract
A system for equalizing pulse to pulse energy of a light beam includes a group of optical devices including an optical device configured to exhibit nonlinear properties, e.g., higher order or third order nonlinear properties. Transmission properties of an unequalized light beam passing through the group of optical devices change such that an output intensity of a resulting light beam output from the optical devices is equalized. One example configuration includes at least first and second prisms having nonlinear properties, i.e., higher order or third order, and configured as a beam steering system.
