Laser marking is literally everywhere - from the keys on laptops and car dashboards to the milk carton in the fridge, the logo on golf clubs to the instruments used by surgeons. In fact, marking is one of the biggest uses of lasers today because it has many advantages over other methods such as printing. As an example, lasers can easily create a permanent mark on most materials that will not peel or smudge, even with frequent handling.

Choose from the widest range of permanent laser marking systems.Coherent's wide range of lasers allows you to mark almost any material. COHERENT lasers are suitable for all industries and continuous operation, including work in clean rooms.

Key features of COHERENT lasers for demanding industrial applications:

Vision

COHERENT lasers enable "pre-marking" of mark position, orientation and size to increase accuracy, reduce tooling costs and increase process yield.

Mark verification

Coherent lasers enable automatic verification of marked 1D and 2D codes and alphanumeric characters after marking. The laser documents and archives the result of the verification for future reference.

Automation

Tray stackers and robots integrated into COHERENT laser systems maximize the throughput of the marking process and minimize labor costs.

Lifetime

COHERENT lasers are designed as industrial lasers to achieve many years of service life with minimal downtime.

Serviceability

Lasers with 100% on-site serviceability, without the need to send the laser to the manufacturer for service.

Extended warranties

COHERENT's service support and Product Activity Plus service offers to ship a new laser within 48 hours of reporting a failure in the event of a fatal failure, minimizing downtime.

3D marking

Simplify marking curved, stepped, loose and recessed surfaces with automated "smart" 3D marking solutions that combine our innovative hardware and software.

Black marking

COHERENT picosecond lasers enable permanent, corrosion-resistant black marking for logos, function marks and/or tracking on stainless steel and aluminum.

Contrast marking of plastics

Permanent high contrast marking of plastics, including electronic components, pharmaceutical packaging, medical devices and consumer products.

Engraving / 3D Engraving

Quickly execute and complete laser engraving jobs using our 3D graphical interface. For distortion-free engraving even on complex 3D surfaces.

Grayscale marking

COHERENT laser machines for greyscale marking of plastics use a modulator outside the laser cavity to ensure precise control of the laser power and the degree of darkening of light-sensitive plastics.

Day/night marking

With COHERENT lasers, you can create sharp, highly legible day and night marks, even on freeform parts, with minimal job setup times and fast throughput.

COHERENT Twin Laser Systems

COHERENT Twin lasers feature two coordinated laser markers that enable high-speed serialization marking on semiconductor integrated circuits, significantly increasing throughput and reducing operating costs.

Step and repeat marking

COHERENT lasers support automated marking of large-scale nested parts. Lasers coordinate marking and motion actions with precise part position changes, often using multiple axes.

Marking on the fly

Laser pulsing can be automatically synchronized by COHERENT PowerLine lasers with the movement or rotation of moving parts, allowing marking without stopping or interrupting motion.
