Laser marking is a marking method that uses a focused laser beam to alter the surface of a target. The laser beam is emitted by an oscillator and scanned using a mirror (known as a scanning mirror), and a focusing lens is then used to focus the beam on the target and mark it by altering the surface.In simplest terms, laser marking is a permanent process that uses a beam of concentrated light to create a lasting mark on a surface. Typically performed with a fiber, pulsed, continuous wave, green, or UV laser machine, laser marking encompasses a wide variety of applications.Fiber lasers can mark a wide range of materials, though they are optimized for metal marking applications. Their high power makes them perfect for annealing and engraving applications, but they cannot mark transparent objects since IR light passes straight through.

Laser hallmarking was developed in the late 1990s and removes a tiny portion of metal from the article rather than displacing it. This allows us to mark hollow, thin or highly polished items without fear of bruising, scratching or distortion.There are two different types of lasering, one which burns in the mark itself, this is an outline laser mark, and then 'deep relief' laser marking which burns away the metal surrounding the mark.Co2 laser marking machine uses CO2 gas in a sealed tube as a laser source to mark on organic materials like wood, glass, acrylic etc . This laser system is widely accepted for product identification, serial marking, date stamping etc.
