Abstract
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.
Claims33
A method for laser treatment with increased illumination uniformity, the method comprising:
- generating a laser beam to create a first illuminated region at a first location of a target site;
- adjusting the laser beam by oscillating the laser beam through an opto-electric interference to create a second illuminated region at a second location of the target site, such that:
- the first and second regions at least partially overlap to form a combined illuminated region at the target site;
- a uniformity of illumination of the combined illuminated region at the target site is greater than a uniformity of illumination of the first illuminated region at the target site;
- and
- performing treatment at the target site using the combined illuminated region of the laser beam.

A laser treatment system comprising:
- a laser configured to generate a laser beam to create a first illuminated region at a first location of a target site;
- an adjustment device coupled to the laser and configured to adjust the laser beam to create a second illuminated region at a second location of the target site by oscillating the laser beam through an opto-acoustic interference;
