Abstract: |
A laser treatment apparatus wherein a tip member formed of a light-transmitting material having a low thermal conductivity and a high heat-resistant property is integrally welded to the tip portion of a fiber waveguide member connected to a laser beam source. A connecting portion having substantially the same diameter as that of a core portion of the fiber waveguide member is integrally formed on the tip member so that end surfaces of the connecting portion and of the core portion are integrally welded to each other. A cladding part leading to a clad formed on the circumference of the core portion is formed on the outer peripheries of the connecting portion and of a welded portion between an end surface of the connecting portion and an end surface of the core portion. External portions of the fiber waveguide member and of the tip member are connected to each other through a sleeve.
