What Is a Laser Marking Machine? How Is It Used? What Are the Benefits and Drawbacks?

Laser Marking: Laser marking, which uses a focused light beam to leave a permanent mark on a surface, is done with a laser marking machine. Pulsed lasers, fiber lasers, green lasers, continuous wave lasers, or ultraviolet laser machines are commonly used for this procedure. Titanium, steel, copper, aluminum, plastic, porcelain, wood, glass, and cardboard are just some of the many materials that can be laser-marked. Graphics, ID numbers, barcodes, and 2D data matrices are all examples of machine-readable markings.

Summary of the Laser Marking Machine

A focused beam of light is used to mark the surface of the material in a laser marking apparatus. The properties and appearance of the material are altered as the beam makes contact with them. Laser marking machines are able to produce clear, legible marks that can be scanned or read from a distance since the focused beam is directed to a specific region. This quality makes laser manufacturing equipment ideal for applications requiring durability and precision. For more info visit


A laser beam is created when an atom is excited to release photons, and those photons are then focused on the surface to be marked. The lengths of the produced energy waves, in nanometers or wavelengths, are the units of measurement. The laser beams intensity decreases as the wavelength decreases and vice versa. For instance, UV laser markers, with a wavelength of 355 nanometers, have less power and are used for marking heat-sensitive materials like glass and plastic, while also being acceptable for soft and organic products due to the reduced risk of material burning.

Fiber lasers, with a wavelength of 1070 nanometers, are very effective at marking tough materials like metals. In contrast to labeling and printing, laser marking does not require any upkeep.

Various Forms of Laser Markers

Laser engraving can be done on a wide variety of materials, from plastics and metals to wood, glass, ceramic, paper, and stones, each of which requires a specific kind of laser marking odisha discom.

A few examples of laser markers are:

1 Laser Fiber

In today’s modern world, this marking technology is ubiquitous. As the most powerful laser markers now available, fiber laser marking machines require a power output of 20 to 50 watts. Engraving and three-dimensional etching are two applications ideally suited to fiber lasers. They are frequently employed when great resolution at high power is required, such as when working with hard metals. Thin metals can be cut, and a large number of small components can be marked, all thanks to the lasers’ small spot sizes and great beam quality.

  1. Laser Ultraviolet

Ultraviolet refers to the portion of the electromagnetic spectrum with wavelengths between 100 and 400 nm. They’re shorter than regular light but longer than X-rays. Longer-wavelength ultraviolet light, which can cause chemical reactions that make things glow or fluoresce, is not used to ionize atoms because its photons don’t have enough energy to do so. UV-emitting devices are manufactured using diodes, solid-state lasers, and gas lasers. In general, UV laser marking machines are built with a 355 nm wavelength, which allows them to mark a wide variety of substrates. Because they don’t generate heat like lasers do, they work great for cold-marking applications. Glass, ceramics, and plastics are among the things they can etch.
