<p>A large area of skin is uniformly irradiated with a laser beam. Two lines of semiconductor laser diodes are staggered, that is, one of semiconductor laser diodes of one line is located in a position corresponding to the center of the two semiconductor laser diodes of the other line. The beams of one line of the semiconductor laser diodes make an angle with those of the other line so that the focal points of the semiconductor laser beams may be brought into line. A large number of laser beams are arranged in line, the area of skin irradiated with the laser beams at a time is increased, and the efficiency of beauty treatment such as skin care and hair removal is improved. In addition, the density of distribution of the focal points of the laser beams is high, the intensity of the local irradiation is averaged, and uniform cosmetic treatment is realized.</p> |
