Our fiber lasers save energy — and that is promoted!

With our modern fiber lasers, you can really save energy. This not only reduces your electricity costs, but also reduces your CO2 emissions. The federal government provides 500€ for every ton of CO2 saved for companies, and even 900€ for SMEs. We work with certified energy consultants to make the most of the funding pools for you.

Fiber laser conveying - what is possible?

Companies generally have the choice between Purchase of a new fiber laser and the Replacing an old laser with a new fiber laser. With federal funding for energy efficiency in industry, there is up to 40% funding, which is calculated on the reduction of CO2 emissions in tons. SMEs receive 900 euros per ton of CO2 saved per year, for For large companies, it is 500 euros per ton of CO2 saved in the year. Overall, the Savings set at a maximum of 40 percent funding for SMEs and 30 percent for large companies.

How do we help with funding?

There are a number of bureaucratic hurdles to receiving funding, particularly in the application process and project description when purchasing or replacing an “old” CO2 laser with a modern fiber laser. Together with an energy consultant, we enable our customers to obtain funding unbureaucratically and easily as part of the purchase process. At this point, of course, it should be said that the computer is only a preliminary estimate. The final funding amount may differ. If you have any questions about this, feel free to contact us at any time!

What are CO2 lasers?

The CO2 laser refers to a laser class of different designs from the group of gas, molecular and infrared lasers in the mid-infrared. being The laser medium is carbon dioxide with a 4-level system. Output powers of up to 80 kW and pulse energies of up to 100 kJ can be achieved. A CO2 laser produces a beam of infrared light with a wavelength in the bands of 9.4 and 10.6 µm. CO2 lasers are quite powerful and, above all, comparatively inexpensive, which is why they are still used today in industrial material processing. However, they have an efficiency of consistently below 20%.

What are Nd:YAG lasers?

How to count fiber lasers crystal laser to solid-state lasers. These are diode-pumped, even via flash lamps. The most common laser types among crystal lasers are Nd:YAG laser (neodymium-doped yttrium aluminum garnet). Crystal lasers have wavelengths comparable to fiber lasers, but they have expensive pump diodes as wear material. These must be replaced after around 8,000 to max. 15,000 laser hours. The crystal itself also has a significantly lower lifetime than the fiber laser. They are therefore an alternative to fiber lasers with similar peak performance, yet with significantly higher wear and, above all, a significantly lower efficiency of less than 5%.

How do fiber lasers work?

A fiber laser is a special form of solid-state laser. The doped core of a glass fiber forms the active medium in a fiber laser. It is therefore a glass laser with optical waveguide properties. The laser radiation, which is conducted through the laser-active fiber, experiences a very high amplification due to its long length. Fiber lasers are generally optically pumped by coupling radiation from diode lasers parallel to the fiber core into its jacket or into it itself. Double-coated fibers allow higher outputs; from the thick jacket, the pump radiation is distributed into the active fiber core. Fiber lasers have unique properties, such as electro-optical efficiencies up to over 30%, outstanding beam quality (with M² < 1.1 for single-mode fiber laser construction, M² < 1.2 for double-clad fibers), high durability (> 20,000 h) and one compact, maintenance-free and robust design. The pulse mode extends into the FS range and can high peak intensity achieve.

Why are fiber lasers the most advanced?

The limited efficiency and effectiveness of Nd:YAG lasers, but especially the even older CO2 lasers, results directly from physical phenomena, not from technological limitations in their production. Fiber optic technology is currently the most modern method for laser processing. It is characterized by exceptional efficiency and effectiveness. Fiber lasers are many times more efficient than CO2 lasers and therefore consume much less energy. Die energy efficiency of fiber optic lasers is included 35%. This value is much higher than for CO2 lasers and ND:YAG lasers with a Efficiency of approx. 5%. Taking these factors into account, the Cost of operating fiber lasers related to electricity up to ten times lower be as with a CO2 laser or Nd:YAG laser. Another advantage of fiber lasers is the much shorter light wavelength, which enables a higher energy concentration in the focused beam. This higher energy density enables faster laser processing at lower power. Melting a narrower gap requires less energy and therefore the specific laser power enables either faster and/or much more precise processing. In addition, can Fiber laser highly reflective metals such as copper process what was not possible with CO2 lasers. Before high-performance fiber lasers were manufactured, laser discs appeared on CO2 lasers. They produce the same wavelength as fiber lasers, but the resonator is of the “free beam” type. In this solution, the active medium is also glass doped with ytterbium, but in the form of a thin disk. In this case, the light must leave the active medium before it is reflected by the mirror and returns to it. Each passage through the glass-air interface causes some losses that do not make it possible to achieve as high an efficiency as with fiber lasers, where the light does not leave the glass until it reaches the head. This enables higher efficiency and lower maintenance costs.
