Laser light irradiation apparatus

A laser light irradiation apparatus comprising:

• a plurality of optical fibers for transmitting laser light from a laser light generator to a fore end portion of said optical fibers, each optical fiber having a base portion which receives and transmits the laser light from the generator and a fore end portion which discharges laser light, wherein the base portions of the optical fibers are twisted together in a bundle and the fore end portions of the optical fibers are untwisted and parallel to each other;
• a laser light emitter contacting the fore end portions of the optical fibers to receive the laser light from the fore end portions of the optical fibers for emitting the laser light from all of the fibers;
• and
• a surface layer formed on at least an emitting face of said laser light emitter, wherein said surface layer comprises laser light absorbing particles and laser light scattering particles which have a larger refractive index than that of said laser light emitter.
