LASER GENERATION DEVICE

摘要

The present invention relates to a laser generation device capable of increasing a therapy effect and, more particularly, to a laser generation device comprising: a laser control unit to output a pulse width modulation signal to output a laser; a pulse generation unit connected to the laser control unit to generate a pulse signal having a corresponding width by receiving the pulse width modulation signal; and a laser output unit connected to the pulse generation unit to output the laser according to the pulse signal received from the pulse generation unit, wherein the pulse generation unit includes: a modulation signal input terminal to introduce the pulse width modulation signal into the pulse generation unit; at least one pulse delay unit to receive the pulse width modulation signal through the modulation signal input terminal and delay the received pulse width modulation signal to output the delayed pulse width modulation signal when turned on by receiving an ON or OFF signal from the laser control unit; an AND and OR gate connected to the modulation signal input terminal and the pulse delay unit to receive and calculate the pulse signal output after being delayed by the modulation signal input terminal and the pulse delay unit; and a pulse selection unit connected to the laser control unit, the AND and OR gate, and the laser output unit to selectively output the pulse signal calculated by the AND and OR gate to the laser output unit according to a control signal of the laser control unit, thereby increasing a therapy effect by varying the output of the laser during the irradiation of the laser.
