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.본 발명은 레이저 발생장치에 관한 것으로서, 더욱 자세하게는 레이저(laser)를 출력하기 위하여 펄스(pulse)폭 변조 신호를 출력하는 레이저 제어부, 상기 레이저 제어부와 연결되며, 상기 펄스폭 변조 신호를 전달받아 해당하는 폭을 가진 펄스 신호를 발생시키는 펄스 발생부, 그리고 상기 펄스 발생부와 연결되며, 상기 펄스 발생부에서 전달받은 상기 펄스 신호에 맞춰 레이저를 출력하는 레이저 출력부를 포함하며, 상기 펄스 발생부는 상기 펄스폭 변조 신호를 상기 펄스 발생부로 유입하는 변조신호입력단자, 상기 변조신호입력단자를 통해 펄스폭 변조 신호를 입력 받고, 상기 레이저 제어부로부터 ON 또는 OFF 신호를 입력 받아 ON 상태일 때, 입력 받은 상기 펄스폭 변
