The TRUMPF CO2 lasers in the TruFlow series have been used in industry as universal standard tools in material processing for years. The flow lasers cut, weld, and treat the surfaces of two- or three-dimensional parts in a reliable and cost-effective way. The wavelength of 10.6 µm and the large power spectrum from 2 to 20 kW gives a great degree of freedom in the selection of material type and thickness. TruFlow lasers not only process metal, but also organic materials, compound materials, and glass.
In CO2 lasers, high laser power and good beam quality depend directly on the length of the resonator. The special construction of the TruFlow folds the quartz tube, which is several meters long, into a square circuit on two levels. Due to this square design, the resonator is mechanically robust and temperature-resistant.
The cooling concept and intelligent energy management make TruFlow lasers the most energy-efficient CO2 lasers. Even under the toughest conditions, TruFlow lasers operate extremely cost-effectively and with high availability. The power range is from 2 kW to 20 kW – so the laser covers a broad field of applications.
TruFlow laser resonators are assembled in the cleanroom and receive their basic adjustment there. This basic adjustment lasts for the laser’s entire lifetime as a result of the patented mounts for the deflection mirrors.
Optical elements can be integrated directly in the laser for encapsulated beam formation in a space-saving manner, e.g. a phase shifter, circular polarizer, diameter adjustment mirror, or beam telescope. In this way, the output beam can be set individually.
Wear-free laser operation with respect to gas circulation and RF excitation. Radial turbine blowers of TruFlow lasers with magnetic bearings generate unique gas flow rates. Contact between the interior of the resonator and the outside world is avoided and the system functions without wear.
