PURPOSE: An apparatus and method for generating laser are provided to prevent excessive blood collection by using Er:Yag laser with wavelength of 2940 nm. CONSTITUTION: A display unit(50) displays the intensity of laser and the charging state of a battery. A switch unit(60) switches on and off power, controls the intensity of the laser, and emits the laser. A safety device(80) is composed of first to third contact parts. A control unit(70) controls a driving unit and the display unit. A reflector includes a first space and a second space. A xenon tube emits light to the first space. A crystal rod amplifies light and oscillates the laser in the second space. A capacitor applies a voltage to the xenon tube. The driving unit charges the capacitor. A battery supplies power to the driving unit. |
