ABSTRACT:
A laser light emitter used in a medical treatment has an optical fiber which extends in a longitudinal direction and at the fore end portion thereof. The core of the fore end portion is not surrounded by a clad but exposed to serve as a laser light emitting portion. A holder supports the optical fiber. Part of or the whole of the emitting portion bends at a certain angle on a longitudinal cross section of the extending direction of the optical fiber. To ensure fixing of the optical fiber to the holder, the optical fiber preferably has a circular cross section, and the holder comprises a thin plate with a concave shaped recess along the edge to which the optical fiber is mounted. The optical fiber extends along the inner surface of the concave shaped recess along the edge of the holder and is fixed thereto by a heat resistant adhesive. To use the emitter in surgery, the holder is connected to a fore end of a hand piece held by an operator. The holder substantially supports the exposed core portion of the optical fiber and a base portion of the optical fiber.
