A medical laser device having excellent operability is provided. A laser main body having an optical fiber laser that outputs invisible pulse laser light, a guide light source that continuously oscillates guide light composed of visible light superimposed on the invisible pulse laser light, and control for controlling the laser main body. In the medical laser apparatus that includes at least the device 30 and the switching device 60 having the repetition cycle setting switch 61 and the energy setting switch 62, and the laser main body 40 and the switching device 60 are provided via the control device 30, The oscillation intensity and oscillation interval of the guide light are linked to the intensity of the invisible pulse laser beam. The guide light source is an LD or LED. The optical fiber laser includes a rare earth element-doped fiber made of fluoride glass to which at least one selected from erbium, holmium, and praseodymium is added. [Selection] Figure 1 |
