Patent number: 7329252Abstract: An apparatus for laser depilation according to the present invention uses a semiconductor laser diode, which is controlled in respect of its energy level, thereby permitting an economical, effective and safe cosmetic treatment. The power output of light of the semiconductor laser diode ranges from 5 to 1500 mW, and the peak wavelength ranges from 600 to 1600 nm. The controller of the semiconductor laser diode comprises pulsating power output control means and radiation period control means for setting a desired length of time for radiation. With these control means the energy level of the beam of light from the laser may be so controlled that a strong beam of light may be thrown for a relatively short time, or that a weak beam of light may be thrown for a relatively long time. Thus, hairs of different thickness and colors can be removed.Type: GrantFiled: May 19, 2000Date of Patent: February 12, 2008Assignee: Ya-Man Ltd.Inventors: Iwao Yamazaki, Yoshihiro Izawa

Patent number: 6736807Abstract: 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.Type: GrantFiled: May 31, 2002Date of Patent: May 18, 2004Assignee: Ya-Man Ltd.Inventors: Iwao Yamazaki, Yoshihiro Izawa
