Highest Reliability – Lowest Maintenance Effort
Laser cutting, laser welding or surface treatment – the diffusion-cooled CO2 Slab laser from ROFIN is not only an excellent cutting laser but also the perfect tool for a wide variety of applications. The trend-setting principle of the Slab laser 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. In addition, the excellent beam quality of K = 0.95 makes the fastest cuts and deepest weld seams. With its excellent attributes and high efficiency, the ROFIN Slab laser has become a mainstream tool in countless production lines around the world.
CO2 SLAB Lasers
Diffusion-Cooled with Minimal Gas Load
A CO2 laser without gas recirculation – how does that work in detail?
The secret for this decisive technology is the two water-cooled electrodes (slabs). High frequency between these electrodes leads to stimulation of the laser gas. The optical resonator is formed by the front and rear mirrors and the two electrodes. The heat generated in the gas is dissipated by the water-cooled electrodes (diffusion cooling). Thus, the conventional gas circulation systems involving roots blowers or turbines are not required.
The crucial advantage of this laser principle is that the laser gas neither needs to be circulated nor to be renewed permanently. That means that turbines and blowers susceptible to deterioration and service are eliminated. Thus, optics integrated into the resonator that are contaminated by flowing laser gas (especially the outcoupling windows) are a thing of the past.
