Abstract
The instrument of the present invention irradiates a relatively large skin area evenly with laser beams. A plurality of semiconductor laser diodes are arranged to form two lines with the semiconductor laser diodes of one line staggered with those of the other line, and the semiconductor laser diodes of each line are so inclined that their laser beams may focus on a single line. With this arrangement the plurality of laser beams provide a linear distribution of narrow beam, and the scanning area on the skin can be expanded accordingly. The beauty treatment on the skin or the depilation treatment can be expedited significantly. Advantageously the focusing points of the laser beams are distributed at an increased density, and the irradiation strength averages everywhere to attain the even beauty treatment.
