In the laser hair removal, laser light is applied to the skin after removing the unwanted hair to cause protein degeneration in the hair papilla and sebaceous glands, thereby suppressing the growth of hair. Methods for removing waste hair include pulling out with tweezers, dissolving with a depilatory cream, and peeling off with a depilatory tape, all of which may damage the skin or cause pain. For this reason, shaving with a safety razor or an electric shaver is the most painless and comfortable hair removal method.

FIGS. 1 and 2 show a front view and a partially cutaway side view of a laser hair removal probe embodying the present invention.
The laser hair removal probe 1 includes a plurality of semiconductor laser diodes 3 that irradiate laser light to both sides of an outer blade 2 of an electric shaver.
Are arranged. The semiconductor laser diode 3 has a through hole a inserted into the heat sink 4 and is fitted therein, and a spherical lens 5 is disposed in front of the light emitting surface thereof. The spherical lens 5 condenses the laser light of the semiconductor laser diode 3 and forms a beam waist at the tip of the outer cutter 2. Note that the semiconductor laser diodes 3 may be arranged on only one side of the outer blade 2. The electric shaver may be a rotary type as well as a vibration type. In the case of the rotary type, a plurality of semiconductor laser diodes 3 are arranged in a ring shape on the outer periphery of a cylindrical head. Instead of an electric shaver, a safety razor may be simply attached to the tip of the probe.

The semiconductor laser diode 3 is inserted into the heat sink 4 as shown in FIG.
And connected to the entrance end of the large diameter optical fiber 7 through
The large-diameter optical fiber 7 is branched into a large number of small-diameter optical fibers 9 via a melt-stretched optical coupler 8, and their emission ends are respectively arranged on both sides of the outer cutter 2 so as to face the rear of the spherical lens 5. Is also good. The coupling module 6 squeezes outgoing light of the semiconductor laser diode 3 with a coupling lens (not shown) and causes the light to be incident at an angle smaller than the light receiving angle of the large-diameter optical fiber 7.

Since the spherical lens 5 has a shorter focal length than an ordinary lens, the light power can be narrowed down to a small and narrow range. Conversely, from the position beyond the focal point, the light beam spreads at the same angle, and the light power is dispersed over a wide range. For this reason, at a position beyond the focal point, the energy density is reduced and the optical power is reduced, so that there is less danger of damaging the living body even if it is erroneously irradiated.
