DC Series

Highest Reliability – Lowest Maintenance Effort

​Laser cutting, laser welding or surface treatment – the diffusion-cooled CO2 Slab laser from Coherent-ROFIN is not only an excellent cutting laser but also the ideal tool for a wide variety of applications. The excellent beam quality of K = 0.95 ensures highest processing quality and increased productivity. With its wavelength of 10.6 µm in the far infrared range, the CO2 lasers are perfectly suitable not only for the processing of metals, but also of wood, plastics – also fiber-reinforced – glass, textiles or paper.


The principle of diffusion cooling provides highest reliability. The laser operates with only a few extremely durable components and does not need conventional gas recirculation – leading to a considerable reduction of maintenance and service. The gas consumption is also minimized: the integrated gas bottle eliminates the need for an external gas supply. Up to the power range of 5 kW, the lasers run with a gas consumption of only 0.1 l/h. Furthermore, the energy-saving standby operation leads to minimal power consumption.

The inclusion of the “Coherent-ROFIN Control Unit“ (RCU) for the Slab Series means that now all products across our high power product range are equipped with the same control platform and comparable interface. The new control offers extended monitoring and control functions, resulting into improved pulse-to-pulse stability, manifold control and log functions including E-Service. For a more comfortable operability, the lasers of the Coherent-ROFIN DC Series are optional available with a mobile operation panel, including touch function. With its excellent attributes and high efficiency, the Coherent-ROFIN Slab laser is nowadays a mainstream tool in countless production lines around the world.

The lasers of the DC Series are available in two configurations:

  • Head/cabinet combination – with wall mountable, space-saving control cabinet (45% space-saving) and optional touchpanel on the control cabinet for easy operation.
  • Compact version – laser head and control cabinet in one compact unit. Due to the closed beam path, the lasers of this Series are now also available as integration module.
