ILLUMINATION VARIABILITY REDUCTION IN LASER TREATMENT SYSTEMS

Technologies are provided for laser treatment with reduced illumination variability. In some examples, a laser beam that creates a first illumination variation at a target site may be adjusted such that the laser beam orientation changes slightly while the laser beam is still being generated. The adjusted laser beam may create a second illumination variation at the target site, and because the laser beam orientation is different the first and second illumination variations may combine to form a combined illumination variation at the target site whose variability is less than the variability of the first or second illumination variations. The more-uniform combined illumination variation may then be used to treat the target site, for example via heat generation.
