A laser device for an endoscope capable of ejecting medical treatment laser beams and illumination light beams into the endoscope through a laser beam probe comprises a medical treatment laser beam oscillator which is received in a housing to emit laser beams, an illumination light source which is received in the housing and includes a turntable with a plurality of different color filters to selectively emit at least two visible rays having different colors, and an optical system which brings the optical axis of laser beams emitted from the oscillator in alignment with the optical axis of visible rays issued from the illumination light source, thereby conducting said laser beams and illumination light beams to a light-emitting section of the housing.
