Abstract
A method for characterizing a laser beam profile is provided. The method includes disposing a laser target, moving the surface of the target, directing a laser to emit the beam at the surface, measuring a reflection from the surface as intensities, and averaging the intensities. The target's surface is disposed substantially perpendicular to an incident direction. The surface is reflective at a wavelength corresponding to the laser beam. The travel direction is substantially parallel to the surface. The laser beam travels along said incident direction to the surface. The reflection represents a plurality of intensities having a distribution of positions along the surface and during a temporal interval. The intensities are averaged over the temporal interval for each position of the distribution to produce an analyzed beam profile. Each position corresponds to a speed along the travel direction based on movement of the surface. The surface can be preferably spun along an axis substantially parallel to the incident beam.
