Method and apparatus for generating laser

An apparatus for generating a laser, comprising:

• on an upper surface of a printed circuit board,
• a display unit displaying a battery charge state and an intensity of a laser;
• a switch unit provided to turn power on/off, adjust the intensity of the laser and control emission of the laser;
• a safety unit comprising first through third contact point parts, wherein the first through third contact point parts respectively contact a body surface as a precondition for generating the laser;
• and
• a control unit controlling the drive unit and the display unit, and
• on a lower surface of the printed circuit board,
• a reflector having a first space and a second space therein;
• a xenon tube emitting light in the first space;
• a crystal rod amplifying the light in the second space and generating a laser;
• a focusing lens focusing the laser and forming a focus;
• a focusing lens installation part in which the focusing lens is installed;
• a capacitor applying voltage to the xenon tube;
• a drive unit charging the capacitor;
• and
• a battery supplying power to the drive unit.
