Abstract

The present invention relates to a laser beam control structure and method. A laser beam control structure of the present invention comprises a handpiece for irradiating laser beams output from a laser beam output device, on a predetermined part; at least one electrode unit positioned at a human body contact portion of the handpiece and receiving hum noise generated from a human body; and a control unit electrically connected to the electrode unit so as to measure the hum noise applied from the electrode unit and to case the laser beams to be irradiated according to the measured hum noise. According to the present invention, there are advantages in that various types of hum noise generated from a human body are measured without applying an electric current to the human body, and a laser beam is irradiated according to the measured hum noise.
