Abstract
A laser irradiation device comprising an optical fiber, a contact probe which irradiates laser light from the irradiation end section thereof, and a holding member which coaxially secures the contact probe and the optical fiber. The device is further characterized in that the irradiation angle of the laser light irradiated from the irradiation end section of the contact probe can be changed while the diameter of the contact probe is standardized, whereby the irradiation angle and diffusion conditions of the laser light can be set and changed as desired to improve the transpiration and coagulation capabilities using a low output laser generation unit, thus reducing the coast of the entire laser irradiation system.
