Marking lasers FL+
Precise, fast, economic - cab fibre lasers

FL+ LogoThe performance and quality of a marking mainly depends from the output power and the laser beam focus. cab FL+ marking lasers are diode-pumped and air-cooled. They have high beam quality and pulse peak power. Laser source output powers are from 20 to 50 Watt.

Different plano-spherical lenses allow marking in fields from 69 x 69 to 290 x 290 mm. Marking is possible on plastics and metals as well as on coated surfaces.

FL+ marking lasers consist of two units: The control unit has a laser source already integrated. The scan head is connected to the laser source via a fiber. It may be assembled in all possible position.

cab marking lasers stand for

  • innovative technologies,
  • focus on smallest spaces,
  • high marking speeds,
  • flexibility,
  • resistancy

The control unit with the laser source are incorporated in a 19’’ rack.

Sample applications

cab marking laser systems mainly work with metals and plastics. Depending from the requirement and material, different methods are known:


Evaporation with high energy density removes the material. An indentation with a sharp outline occurs.

QR codes for traceability

Traceable QR encoding

Cast parts

Cast part marking


is mainly applied with highly alloyed stainless steel as well as with titanium.


Medical instruments

Traceability in sterilization processes

Traceable sterilization


The laser ablates the top layer to uncover the underneath material. Examples include anodized layers or paint coatings.

Aluminum nameplatesAluminum rating plates


Automotive components

Automotive components


is applied with plastics. The way the color changes depends from the chemical composition of the material as well as from ingredients and fillers.
