Description

  The present invention is an apparatus for generating and irradiating laser light that does not depend on the Q-switch system, and is a small and light laser diode light having a simple structure suitable for hair removal and stain removal for beauty and the like, which can be used safely and easily. It relates to a direct generator.

  Laser light oscillation forms include CW (continuous wave) pulses and single pulses. When a high peak laser light is generated with a short pulse of 1 μs or less, the Q-switch method is usually used. However, the laser generator using the Q switch method has a complicated structure, becomes large and heavy, and it is not easy for a human to use it with one hand.

  By the way, the conventional epilation device using laser light reflects the laser beam irradiated with a small spot diameter sequentially by the first and second adjustable tilting mirrors whose axial directions are different by 90 degrees to thereby adjust the coordinate axis. There is one that scans in the X-axis direction and the Y-axis direction and detects the irradiation state by an image sensor so that the irradiation of the laser beam is adapted to the target position (Patent Document 1). However, the pulse width of the laser beam is considerably large as 1 ms to 100 ms (the specific structure of the laser source is not clearly shown), and the same portion is irradiated with the laser beam repeatedly due to an operational error or the like. Doing so or prolonging the exposure time may cause irritation and burns to the skin. Furthermore, since there is no means for preventing the unexpected irradiation of laser light, there is a problem in safety in this respect, and the structure is complicated, the size is increased, and the weight is increased. However, there is a drawback that it is difficult to use in a depressed part of the human body.

  In addition, a single polygon motor or electromagnet-driven diaphragm having a mirror surface is arranged inside the casing in this type of epilation device, or the first and second polygons whose axial directions are different by 90 degrees. A motor or electromagnet-driven diaphragm, or scanning means that reciprocates the laser diode itself in the X-axis direction by a crank mechanism, or a bundle of optical fibers and a built-in optical fiber An optical scanning means is provided by making an external laser beam scanning device face the rear end of the fiber so that the laser beam emitted from the laser diode is optically irradiated in the coordinate axis X-axis direction. There is one that can efficiently perform a hair removal operation by irradiating the body hair with laser light (Patent Document 2). However, there is no indication as to what kind of characteristics the laser beam is used for, for example, the pulse width or peak power of the laser beam, and there is a risk of causing inflammation or burns in the skin in some cases. There is a risk of causing irritation and burns on the skin even if the same part is irradiated with a powerful laser beam or the irradiation time is prolonged. Of course, in this case as well, there is a problem in safety because there is no means for preventing the unexpected irradiation of the laser beam. In addition, since the laser diode of the laser source is separated from the driver device, the so-called pulse current becomes dull and there is a disadvantage that a high-peak laser beam cannot be obtained with a short pulse.

  In addition, an interlock sensor is installed around the laser emission port of the casing, and when the interlock sensor is pressed against the human skin surface during use, the laser light generator is activated, and when it is separated, the operation is automatically performed. There are some which are designed to be blocked (Patent Document 3, Patent Document 4). However, since these interlock sensors employ a pressure switch system, the tip is pushed in, and the irradiation distance and irradiation position of the laser light fluctuate, and there is a drawback that stable and good irradiation cannot be obtained.

  FIGS. 1 to 3 show embodiments according to the laser diode optical direct generators of claims 1, 2, 3, 7, 8, and 9. Will be described in detail.

  As shown in FIG. 1, a laser diode light direct generator 1 is connected to an external power supply device 7 via a power supply cable 6, and the power supply device 7 converts an AC supplied from a household AC power supply to an appropriate value. It is converted into a direct current and supplied to the laser diode light direct generator 1 through the feeding cable 6.

And an auto-scanning device 2 that scans in the Y-axis direction and the Y-axis direction, respectively, and an appropriate DC power supply current supplied from the power supply device 7 to the high-speed driver device 4 is manually turned on at an appropriate position on the casing 20・ Equipped with a start / stop switch 5 for turning off, a laser scanning lens 17 at the laser exit 9, and , The outer edge of the laser exit 9, the interlock sensor device 8 for electrically preventing the operation of the high speed driver apparatus 4 unless in contact with human skin surface is equipped.

  As shown in FIG. 3, the laser diode device 3 includes a laser diode 19 that emits laser light under the control of the high-speed driver device 4 and a focal length adjustment lens 18 for the laser light. The driver device 4 is arranged in the immediate vicinity of the laser diode 19 and controls the laser power supply unit 16 to emit a high-peak fine laser beam, that is, a spot laser beam, to the laser diode 19 with a required short pulse. It consists of a CPU unit 12. The CPU section 12 is turned on / off by the pulse width control section 13 and the frequency control section 14 for the laser power supply section 16, the start / stop switch 5 and the interlock sensor device 8, and the laser power supply section 16 and the frequency control section 13. The sensor control / switch unit 15 controls ON / OFF of the pulse width control unit 14 and the auto scanning device 2.

  The auto-scanning device 2 includes an electromagnetic coil driving unit 10 that reciprocally scans the laser light emitted from the laser diode device 3 in the X-axis direction and the Y-axis direction (see FIG. 5), and a laser light scanning lens 17. And an electromagnetic coil drive control unit 11 for controlling the electromagnetic coil drive unit 10. The ON / OFF control by the sensor control / switch unit 15 in the auto-scanning apparatus 2 is performed by the electromagnetic coil drive control unit 11. It is configured to be done. The auto-scanning device 2 may be a piezo (piezoelectric) type drive or a mechanical cam type drive, and a suitable drive unit and drive control unit are provided for these.

  The interlock sensor device 8 shown in FIG. 1 to FIG. 3 is a micro electrical contact switch system that can provide stable and good irradiation without causing a change in distance or position in laser irradiation without mechanical movement. I have to.

  In the high-speed driver device 4, an appropriate value of direct current is supplied from the external power supply device 7 to the laser power supply unit 16, and a frequency within 16 kHz is given to the laser power supply unit 16 by the control of the frequency control unit 14 of the CPU unit 12. A pulse width of about 1 μs or less is given by the control by the width controller 13 (see FIG. 4), and a pulse current of a maximum of 30 A at that frequency and pulse width is generated. This pulse current is used as the laser diode 19 of the laser diode device 3. And the laser diode 19 is turned on to output a short pulse laser beam with a peak power of 25 W, a peak energy of 25 μJ, and an average power of 0.4 W from the laser diode 19, and this is output to the focal length adjusting lens 18. Condensed by a short pulsed fine laser beam with a spot diameter of about 0.1 mm to 0.3 mm That is, a spot laser beam is obtained, and further, in the scanning device 2, the spot laser beam is moved to a coordinate axis X within a range of about 2 mm to 10 mm square by the operation of the electromagnetic coil drive unit 10 controlled by the electromagnetic coil drive control unit 11. Reciprocating scanning is performed at intervals of 0.02 mm to 0.08 mm in the axial direction and the Y-axis direction (see FIG. 5), and the laser beam is emitted from the laser emission port 9 to the outside as square laser light.

  In use, the casing 20 of the laser diode light direct generator 1 is gripped with a palm, the micro electric contact switch type interlock sensor device 8 at the tip is brought into contact with the skin surface, and the laser emission port 9 is opposed to the treatment site where the skin surface should be removed and the stain is removed, and the start / stop switch 5 is turned ON. At this time, the micro electric contact switch type interlock sensor device 8 that is in contact with the skin surface generates an electrical signal in accordance with the contact, and the CPU section 12 is operated in the high-speed driver device 4 by this electrical signal. Then, the laser power supply unit 16 works and the laser diode device 3 and the auto scanning device 2 operate to generate the above-described square laser light, and this square laser light is emitted from the laser emission port 9 to the outside. In addition, it is necessary to move the laser emission port 9 appropriately according to the situation of the processing location.

  Since the laser power supply unit 16 of the high-speed driver device 4 is arranged in the immediate vicinity of the laser diode 19 of the laser diode device 3, the laser diode device 3 can be efficiently integrated into a state where the pulse current is less dull. In this case, even if the laser diode 19 is a low-power and inexpensive one, the laser diode 19 can emit a high-peak laser beam with a short pulse, and this laser beam is condensed by the focal length adjusting lens 18. The laser diode device 3 can efficiently emit a spot laser beam having a required short pulse and a high peak, and this spot laser beam is reciprocally scanned by the autoscanning device 2 in the coordinate axis X-axis direction and the Y-axis direction. Thus, the above-described square laser beam is obtained, and this square laser beam passes through the scanning lens 17. Is irradiated from the laser exit 9 to the processing portion of the collected hair and skin blemishes Te. This square laser beam can be efficiently absorbed by the melanin pigment at a place where the melanin pigment is present on the skin, and can be irradiated as a laser beam having a wavelength of about 800 nm that appears red to the human eye. That is, by shortening the pulse width to 1 μs or less, the tissue located at a certain distance from the melanin pigment is heated excessively for heat conduction even when irradiated with a high-peak laser beam with an input current of 30 A. In addition, the laser light can be stably and satisfactorily irradiated by the micro-electric contact switch type interlock sensor device 8 without variation in irradiation distance and position, and the skin can be damaged such as burns. No, required hair removal and stain removal can be performed efficiently and safely. In addition, because of the short pulse, even if a large current is passed through the laser diode, the temperature at the end face does not rise, so there is no need to use a large-capacity and expensive laser diode, nor a complicated, heavy and expensive Q-switch system. Since a laser diode having a small capacity can be used without hindrance, a low-cost laser generator having a simple structure, small and light, and easy to use can be realized.

  When the laser diode light direct generator 1 is separated from the human body for some reason during use, the interlock sensor device 8 is separated from the skin surface, and the electrical signal from the interlock sensor device 8 is stopped. The apparatus 4 and the auto-scanning apparatus 2 are stopped, and the laser diode light direct generator 1 is put into a resting state as a whole. Therefore, the emission of the square laser light is stopped, and safety can be ensured.

  In the second embodiment, the spot laser beam in the first embodiment is a line laser beam, and the line laser beam having a length of about 2 mm to 10 mm is reciprocally scanned in the coordinate axis X-axis direction to a width of about 2 mm to 10 mm to 2 mm. A square laser beam having a size of about 10 mm square is obtained, and the square laser beam is irradiated from the laser emission port. In this case, the electromagnetic coil driving unit 10 according to the first embodiment does not require scanning means in the coordinate axis Y-axis direction.

  Next, FIG. 6 shows an embodiment according to the laser diode optical direct generator of claims 1, 4, 5, 6, 7, 8, and 9. Hereinafter, this will be described in detail.

And a Y-axis drive mirror 27y for further deflecting it in the direction of the coordinate axis Y-axis. The mechanical cam type drive mirror 27 may be an electromagnetic coil type drive mirror, a piezo (piezoelectric) type drive mirror, or the like. In the case of these drive mirrors, the mechanical cam type drive mirror 34 is replaced with the mechanical cam type drive mirror 34. A drive control unit suitable for the drive mirror may be used.

  The optical and electronic detection device 29 includes an image condensing lens 44 that accepts an image, and a camera unit 45 that converts the image that has passed through the image condensing lens 44 into an electrical signal and outputs the electric signal. The video output signal from the camera unit 45 is sent to an external monitor 46 to be imaged and observed. The camera unit 45 is preferably composed of a small CCD, CMOS camera or the like.

Next, the laser diode 25 is turned on with this pulse current, The laser diode 25 outputs a short pulse laser beam having a peak power of 25 W, a peak energy of 25 μJ, and an average power of 0.4 W, and the laser light is condensed by a focal length adjusting lens 30 to be spot diameters of 0.1 mm to 0.00 mm. A spot laser beam having a short pulse of about 3 mm is obtained, and further, electric is performed by the mechanical cam type drive control unit 34 of the auto scanning device. In the mechanically controlled cam mirror 27, the spot laser beam is slowly moved in the range of about 2 mm to 10 mm square by the X axis driving mirror 27x and the Y axis driving mirror 27y in the coordinate axis X axis direction and the Y axis direction.
