LASER SYSTEM FOR THE MARKING OF METALLIC AND NON-METALLIC MATERIALS

摘要

A laser system for the marking of metallic and non-metallic materials comprising a laser oscillator (1), characterized in that said laser oscillator (1) comprises: an active optical means (13) of the crystal laser type, a laser pump (10) to provide a pump energy to said active optical means (13); a mirror (14) disposed upstream said active optical means (13); an optical switch, apt to provide a pulsed laser beam, disposed downstream said active optical means (13); a mode adaptor (18) coupled to said optical switch (16); a predetermined length single-mode optical fibre (19), coupled to said mode adapter (18); a Bragg Grating type reflector coupled to said optical fibre (19).
