Abstract

The present invention provides a method for marking animal or plant living body crust under the condition of no damaging living body and its equipment for using said method. The described equipment to formed from laser generator, light-conducting arm, X and Y vibrating mirror, graph generator, F theta lens and light-conducting cylinder. The laser beam produced by laser generator is reflected or refracted by means of one group of lens and focussed on the living body material on the working table under the control of graph generator and a certain pattern is formed on it. Said method is simple and easy to implement, and the mark formed by said method is not easy to be fallen off when it is worked at high temp. or soaked in water.
