Fiber laser technology
The fiber laser is a system for fiber laser marking and belongs to the so-called solid-state lasers. In this process, the laser light from a diode laser is guided over a very long distance through an optical glass fiber and amplified. This produces an extremely intense laser beam with outstanding beam quality. A pulsed fiber laser with a pulse duration of 100 nanoseconds is usually used for fiber laser marking.
A fiber laser is an especially type of laser in which the light is amplified by an optical fiber doped with rare earth ions, such as erbium or ytterbium. These ions are crucial for the amplification, as they are put into a high-energy state by pumping with external light sources, often diode lasers. As soon as the ions enter the excited state and then fall back again, they emit photons. These generated photons move through the fiber, exciting other ions and thus amplifying the light.
Fiber lasers offer numerous advantages, including high efficiency, excellent beam quality and the ability to create compact and robust systems. Due to these properties, they are widely used in many areas such as materials processing, medicine and telecommunications.
The REA LASER FL Fiber Laser is ideal for industrial applications as it is compact and easy to integrate into production plants or manufacturing plants. It offers high efficiency and is an economical marking process with low energy consumption. In addition, fiber lasers are virtually maintenance-free and durable.
The REA LASER FL marks products with small texts, codes and logos in high resolution. It is suitable for metals such as stainless steel and titanium as well as plastics and thin foils. Markings are even possible on oily, corroded surfaces or surfaces that are over 1000°C.
