Abstract

Living animals are marked for identification or other purposes by transmitting to surface areas of the skin of the animal through a light-conducting multiple fiber bundle a beam of laser light spatially modulated between the source of the beam and the skin of the animal in selected patterns of an intensity effective to cause irreversible depilation or depigmentation of the hair and/or skin in the target area. The modulation of the laser beam may be effected between the source of the beam and the fiber bundle, between the fiber bundle and the skin of the animal, or in the fiber bundle itself.

Claims

1. A method of marking living animals with identifying indicia which comprises transmitting to the skin of the animal through a light-conductive multiple fiber bundle a beam of laser light spatially modulated between the source of the beam and the skin of the animal in a selected identifying pattern and of an intensity effective to cause irreversible depilation or depigmentation of the hair or skin of the animal.
