Marking Lasers

Laser marking is a process in which the laser beam interacts with the surface of the material slightly altering its appearance, typically turning it black.  Unlike laser engraving where the material is ablated or laser etching where the material is melted, these lasers heat the material causing oxidation under the surface.  To achieve this, marking lasers are typically operated at lower powers and slowly scanned across the material to leave the surface intact.  This process is sometimes referred to as laser coloration or laser dark marking, as well as charring for plastic materials.  Typically, fiber lasers are used for this process due to their ease of integration.  On this page, you will find a list of all of the marking lasers including both pulsed and continuous-wave fiber lasers.
