Laser Weeding
Futonics thulium fiber lasers are suitable for precise, contact-free and chemical-free weed control using laser radiation. In laser weeding, the energy is applied selectively to individual weeds or their growth centers without using herbicides and without mechanically disturbing the soil.
With a wavelength in the 2 µm range, high beam quality and precise focusability, Futonics fiber lasers enable locally confined thermal treatment of plant material. This makes the technology suitable for modern agricultural systems, automated farming robots and sustainable applications in precision agriculture.
Chemical-free alternative to herbicide treatment
Conventional weed control often relies on chemical herbicides or mechanical soil treatment. Both methods can have disadvantages: herbicides are increasingly subject to regulatory and ecological scrutiny, while mechanical methods can stress the soil, require energy and do not always operate selectively.
Laser-based weed control provides a precise alternative. The laser beam can be directed specifically at unwanted plants while crop plants and surrounding areas are spared. This makes laser weeding particularly relevant for automated systems that detect plants and treat them selectively.
Why Futonics lasers are suitable for laser weeding
Futonics offers high-performance thulium fiber lasers with 400 W CW output power and 1200 W QCW peak power. The high power and excellent single-mode beam quality enable very precise focusing of the laser beam onto small target areas.
Compared with CO₂ lasers, a significantly smaller focus spot can be achieved. This results in a higher power density in the target area, enabling faster and more efficient thermal treatment of individual weeds. The compact design and high process stability make Futonics lasers particularly suitable for integration into mobile agricultural systems, field robots and OEM platforms.
Advantages of the 2 µm wavelength compared with 1 µm, 1.5 µm and UV lasers
For laser weeding applications, not only laser power is important, but also the interaction between the wavelength and plant material. Futonics thulium fiber lasers emit in the 2 µm wavelength range and therefore offer a suitable combination of absorption, beam quality, power density and system integration.
Compared with lasers in the 1 µm range, 2 µm radiation is more strongly absorbed by water-rich plant tissue. This allows the laser energy to be delivered more selectively into leaves, stems or growth centers. It supports locally confined thermal treatment and reduces the need for unnecessarily high energy input into surrounding areas.
Compared with 1.5 µm lasers, Futonics 2 µm thulium fiber lasers offer higher available output power while maintaining excellent single-mode beam quality. This enables smaller focus spots and high power densities, which are important for fast and selective weed treatment in automated agricultural systems.
UV lasers can enable very fine processing, but they are generally less suitable for laser weeding. They typically operate at lower power levels, require more complex optical systems and place higher demands on components and safety concepts. For thermal treatment of plant material, high-power 2 µm fiber lasers therefore offer a robust, efficiently integrable and industrially scalable solution.
Futonics 2 µm technology combines high output power, excellent single-mode beam quality and suitable absorption in water-rich plant material. This makes the lasers particularly suitable for precise, chemical-free and automated weed control.
