Abstract
This apparatus includes a laser light source S which irradiates a spatial light modulator (SLM) with a laser beam LR. Individual optical systems are arranged such that the laser beam reflected by the SLM irradiates a region to be treated. When this configuration is used, the laser beam reflectivity can be made much higher than when a transmitting device is used. This allows high-efficiency laser beam irradiation. A predetermined pattern is written in the SLM , and this predetermined pattern is preferably a hologram pattern.
