ABSTRACT:
A laser light emitting probe used in a medical treatment. It has longitudinally a base end to impinge on, a body to penetrate through and a tip end to emit from for laser light, comprising the tip end being covered with a light scattering surface and bending at a certain angle on a longitudinal cross section. Preferably, the tip end is covered with a surface layer containing laser light absorbing particles and laser light scattering particles having a larger refractive index than that of the material of the probe on the surface of at least from the bending part to the end part of the tip end. A producing method of the probe comprising tapering a laser light transmissable member at least at a tip end thereof, bending the transmissible member at the tip end, making contact the transmissible member with a dispersion including at least said two kinds of particles and laser light transmissible particles having a melting point not higher than that of the transmissible member, and baking the transmissible member at a temperature higher than the melting point of said transmissible particles and within a limit as transmissible member can keep its shape.
