FBH presents new developments on the lasers 2009 in Munich

Key components for more efficient material processing systems without it in the automobile industry nothing would run: Robots with ultramodern laser systems are used during the material processing, approximately when cutting or welding of metals. For such applications laser systems with high achievements are in demand, which can be achieved with diode lasers as pumps of solid lasers. Thus a key function comes to them: They are the crucial factor for attainable in principle total output of a laser-based system. The ideal diode laser as pump is characterised by a high efficiency during at the same time high power output. It should besides narrow spectral width and a small reflected beam angle exhibit, with which the jet can be well focused. At the Ferdinand brown institute succeeded developing a diode laser with a very small reflected beam angle from only 15� to with which no reductions must be taken during efficiency and power output in purchase. Commercially available lasers in this wavelength coverage offer a reflected beam angle of typically 27� and more. The FBH laser has a wavelength of 975 nanometers, the standard wavelength of industrial pumping lasers in material processing systems, and supplies an excellent efficiency of 58% and a power output of 7 Watts. For this development at Institut already existing know-how was used and developed further in such a way that an optimal balance between efficiency and far field could be achieved. By the small divergence could be done without a complicated structure of lens. That makes the total structure clearly more simply and less disturbance susceptible. These lasers were manufactured also for the first time on a 4-Zoll-Wafer. With its again established 4-Zoll-Prozess� with lasers Institut reacts to increased performance requirements and future chip developments, which make larger resonator lengths necessary. This laser and further new developments presents the FBH on one to the internationally most important business and Networkingplattformen for the laser technology, attached is the specialized conference CLEO euro PE reference: On the lasers 2009 in Munich, 14. by 19 June, is the FBH on the Berlin Brandenburger group exhibit in resounds to B1, conditions 461 and to the specialized conferences with lectures represented.
