PURPOSE:To thin the tip part for emitting a laser light. CONSTITUTION:The laser probe of a laser light irradiation device of a system for guiding a laser light to position to be irradiated by an optical fiber is constituted of an invisible light optical fiber 1 for guiding an invisible laser light, a visible light optical fiber 2 for guiding a visible laser light, an optical system for condensing the laser light guided by these optical fibers 1, 2 to the same position, and a hollow waveguide 3 for guiding the laser light condensed to this same position. In such a way, the hollow waveguide can be thinned. |
