Abstract
A fiber optic laser conducting probe is used for photodynamic therapy. In this fiber optic laser conducting probe, an optical fiber has an end used for conducting a pulse laser beam. The laser beam is conducted through the optical fiber and irradiated from the end. A end tip is made of polyamide resin. The end tip has a hollow portion, and is attached to the end of the optical fiber such that the pulse laser beam can be irradiated through the end of the optical fiber, through the hollow portion and through the end tip.
