PROBLEM TO BE SOLVED: To provide a laser therapeutic device capable of radiating a laser beam with a high efficiency. SOLUTION: This device comprises a laser beam source S2 for emitting the laser beam LR to a space light modulator(SLM) 11, and each optical system is arranged so that the laser beam reflected by the SLM 11 is radiated into an area to be treated. Since the reflectance of the laser beam can be made sufficiently higher than in the use of a transmission type element according to this structure, the laser beam radiation can be performed with a high efficiency A prescribed pattern is written in the SLM 11, and this pattern is preferably a hologram pattern. |
