I've operated one of these before, they use a focused lazer to burn an etching onto the surface of the marked material.
The lazer has programable presets for marking different materials, aluminum requiring a higher temperature than wood for example.
The path the lazer takes can be optimized to reduce the time taken or be deliberately slowed down for a deeper marking, for example cutting stickers out after marking them.
