This invention is a laser probe made to cure and extinguish within a short time surface-existing tumors generated in a wide range within a body cavity and having a substantially spherical hollow light diffusing part enclosing a light dispersing medium at the tip, light leading fibers inserted in this light diffusing part and a laser light emitting end arranged substantially in the center of the light diffusing part. This laser probe diffuses a laser light emitted from the emitting end of the light leading fibers over a wide range from the light diffusing part to illuminate the objects with a uniform intensity.
