2 ROFIN FL SERIES THE PRODUCT Ideal Beam Quality for Every Application The high brightness fiber lasers of the ROFIN FL Series are the ideal addition to compliment the range of lasers currently offered by ROFIN. With their high performance, they are suitable for classical cutting and welding applications as well as for various high speed, scanner-based applications. The emitted wavelength in the range of 1 µm achieves high absorption in many materials, such that all common solid-state laser applications can be performed using the FL Series laser. With the multi-mode version of the FL laser, fiber optics of 50 to 600 µm can be used. The single-mode version produces exceptionally good beam quality, typically in the range of 0.4 mm x mrad. The excellent beam quality also allows the efficient use of dynamic beam scanner systems for high-speed positioning as well as the fast and precise application of small geometries at workpieces. This reduces cycle times and increases productivity. Beam switches and energy splitters are available as an option, which allows up to four working stations to be operated with only one laser. Non-productive times are reduced and the utilization of the laser is increased. For easy integration into existing machining concepts, the compact version of the fiber laser is available as an alternative system solution. ROFIN utilizes more than 35 years experience with its proven product quality and service concept to achieve the ideal beam for every application.

3 ROFIN FL SERIES THE PRINCIPLE New Peak Performances Thanks to Thinnest Fiber Optics Fiber lasers use special fiber optics as active medium medium, this laser beam does not leave the fiber optic with thicknesses of only a few µm, which produces high before the process optic (single-mode) or the beam switch performance at optimal beam quality. The mirrors of the (multi-mode). Due to this all-in-glass technology, the risk resonator are used as fiber bragg gratings (FBGs) to of contamination of the optics, and therefore a reduction define the wavelength of a fiber laser. of the beam quality, can be eliminated. Pumped light from focused high-power laser diodes create a beam that is coupled by so called pump couplers into the resonator and results in the active fiber excitation. Opposite to common concepts in which the created laser beam switches repeatedly between air and the laser active The laser light is guided by process fibers to the workpiece, where it can be focused for the particular application. The use of innovative scanner techniques for cutting and welding is also possible.

4 ROFIN FL SERIES LASER MACRO THE BENEFIT Absolutely Precise, Absolutely Reliable Optically and electronically modular designed pumping units that are easy to maintain High beam quality allows small focal spots and at the same time large working distances No contamination of processing optics due to the long distance to the workpiece Beam profile of a FL 010 S 1,000 Watt with single-mode Distortion optimized welding mainly smaller components with less or no heat capacity or conductivity High-power densities allow new welding techniques, such as oscillation or wobbling and therefore provide the development of new applications High absorption in many materials thanks to a wavelength in the range of 1 µm Maximum speed while cutting and welding thin materials unachievable with conventional beam sources Variable weld geometries due to a wide range of optical fibers Increased productivity and reduced cycle times with dynamic beam scanner systems: different positions and small geometries at workpieces are approached fast and precisely Fiber-fiber switch and energy splitter for ideal utilization
