Title: LASER TREATMENT APPARATUS
Abstract:
A laser treatment apparatus, wherein a laser light source (S2) for projecting a laser beam (LR) to a spatial light modulator (SLM) (11) is provided and optical systems are arranged so that the laser beam reflected from the SLM (11) is projected into a region to be treated. Since the reflectance with respect to the laser beam is sufficiently higher than that of when a transmission element is used, high efficient laser beam projection can be done. A predetermined pattern written in the SLM (11) is preferably a hologram pattern.
