Patent ID: 7329252

Claim:
An apparatus for laser depilation, comprising: a semiconductor laser diode of which the power output of light ranges from 5 to 1500 mW, and of which the peak wavelength ranges from 600 to 1600 nm; a condenser lens downstream of said semiconductor laser diode; light power output control means for controlling the light power output of the laser beam with respect to the length of pulse-on time; and radiation period control means for setting a desired length of radiation period within the range of 1 to 9 seconds, the length of radiation period thus set alternating with a given length of dormancy period, whereby with the aid of the light power output control means and of the radiation period control means a most appropriate control may be effected in respect of energy level to expose a selected area of the skin to the controlled laser beam, thus causing denaturation of protein in the hair papillae and sebum vessels, thereby suppressing the growth of hairs; a laser projector within which said semiconductor laser diode and said condenser lens are mounted; and a heat sink mounted to said laser projector, wherein: said semiconductor laser diode is mounted to said heat sink.
