The present invention relates to a dual laser outputting device which comprises: a first laser generating unit which irradiates a first laser of first wavelength a second laser generating unit which irradiates a second laser of second wavelength which is different to the first wavelength a mirror unit which reflects the rest laser after outputting the part of the first and the second laser which are irradiated from the first and the second laser generating units to a desired location a reflected amount detecting unit which outputs a signal of the relevant size by detecting the amount of the first and the second laser which are reflected from the mirror unit a controlling unit which is connected to the reflected amount detecting unit, determines the amount of light which is outputted from the first and the second laser generating units by using the signal which is outputted from the reflected amount detecting unit, and outputs a warning signal in case the determined amount of light is less than predetermined value a warning display unit which indicates the abnormal status of the first and the second laser generating units by operating in accordance with the warning signal which is outputted from the controlling unit. Accordingly, the user can recognize whether the amount of laser which is outputted is normal status or abnormal status, and selectively use a laser which has different wavelength according to the selective motion of the user, thereby improving the satisfaction of user and reliability about the product.COPYRIGHT KIPO 2014[Reference numerals] (11) A first wavelength lasing unit (12) A first total reflection mirror unit (13) A first patial reflection mirror unit (21) A second wavelength lasing unit (22) A second total reflection mirror unit (23) A second patial reflection mirror unit (40) A reflecting amount detecting unit (50) A controlling unit (60) A laser selecting unit (70) A warning display unit본 발명은 듀얼 레이저 출력 장치에 관한 것으로서, 상기 듀얼 레이저 출력 장치는 제1 파장의 제1 레
