Abstract
A method, an apparatus and/or a system of laser marking of an interior cavity of a securing means of a substance container is disclosed. In one embodiment, a solid-state laser marking system to mark a securing means of a substance container includes a semiconductor laser to emit a pumping laser beam. The solid-state laser marking system also includes a resonator to create the laser beam that is then focused through a lens to mark the securing means of the substance container having a maximum diameter of 5 cm. Further, the solid-state laser marking system includes a solid-state laser crystal doped with a rare-earth element, to produce a laser beam in response to being pumped by the pumping laser beam and a laser resonator. The laser resonator is configured to focus the laser beam of a spot size of less than 150 microns and a beam quality of M2 less than 1.3.
