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.

Fiber optic laser conducting probe for photodynamic therapy

A plane side of a semispherical lens is opposed to an end of optical fibers for guiding a pulse laser beam, and a semispherical lens is disposed in a predetermined spaced relation.

Optical fiber laser device

A polyolefin resin light diffusion tip is attached to an optical fiber end for conducting a pulse laser beam.

Fiber optic laser conducting and diffusion device

An optical fiber laser device, used as a pulse laser device, has a spherical lens made of optical glass having a refractive index of 2 or less. The spherical lens is provided on an extreme end of an optical fiber which guides a pulse laser beam. An object side of the spherical lens is projected externally of a base housing the spherical lens therein.
