5.1.1 Laser Technology

5.1.1 Laser Technology Together we are strong – networks for laser technology In recent years, a variety of network structures for laser technology have developed in the capital region, which facilitate access to resources such as knowledge or capital for companies and research institutions, both locally and internationally. Actively cooled high-power connector for laser applications in material processing © FCC FibreCableConnect GmbH Thus, laser technology is a focus both within the Berlin-Brandenburg photonics cluster and the competence network OpTecBB. The PhotonikBB network also focusses on laser technology and puts appropriate emphases, for example, on the use of lasers in the solar industry. And the Laserverbund Berlin-Brandenburg uses the passion of its members as engine: it organizes lectures and conferences, visits innovators and giants of industry, and creates opportunities for industry players to communicate. After all, exchange of experience and brainstorming are among the strengths of the laser region Berlin-Brandenburg. to one kilowatt. FiberTech also offers fibers, fiber bundles and fiber probes in various customized versions, plus peripheral components. Leoni Fiber Optics is another European industry leader with a branch office in Berlin. Leonie also offers fibers, fiber bundles and fiber probes in various customized versions, plus peripheral components. Report 2010 Lasertechnik Berlin-Brandenburg A detailed overview of laser technology in Berlin-Brandenburg is provided by the Report Laser Technology, published in 2010 by the TSB Innovation Agency Berlin, and is available for download at www.tsb-optik.de. Optical fibers and fiber systems are also the business of ART Photonics. ART products are used in spectroscopy, for example, and for biopsies and in laser medicine. Fisba Photonics is a German subsidiary of the Swiss Fisba Optics. They settled in Adlershof because of the many competencies available in the neighborhood. Their aim is to strengthen Fisba’s system competences in the area of innovative laser beam shaping optics and control electronics for demanding industrial applications. With a developer team they not only do basic research, but also offer feasibility studies, experimental studies, design and development as well as laboratory samples and prototypes.

Independent developers, such as Optikexpertisen Dr. Volker Raab, help to compile and optimize appropriate systems. 44

5.1.1 Laser Technology “Without the laser, an advanced industry is no longer conceivable” Interview with Prof. Dr. Hans Joachim Eichler about laser technology far-reaching into the future is laser-induced fusion. In contrast to nuclear reactors, very little radioactivity is produced, so that a new generation of safe power plants of high electrical power becomes possible, which only need heavy water as fuel. Photonics is an interdisciplinary technology. In which industries are lasers used commensurate with the current technological level of development, and where is potential? Germany is the world leader in the manufacture and use of lasers for material processing and micromachining. This high level of development needs to be further expanded. Berlin and Brandenburg have to position themselves yet better in national and international competition and increase industrial production. In the excellent medical technology in Berlin, I see the opportunity and responsibility to bring together the existing laser activities and develop a leading position with great economic importance. Prof. Dr. Hans Joachim Eichler is the director of the Laser Group at the Institute of Optics and Atomic Physics (IOAP) of the Technical University Berlin and director of LMTB. His technical skills concern the development of diode- and solidstate lasers, nonlinear optics, stimulated Raman scattering and phase conjugation, as well as spectroscopy with ultrashort laser pulses for the detection and investigation of molecules and biological processes. Other projects include the manufacture and characterization of dielectric multilayer systems for mirrors and filters, fiber optics, as well as silicon nano-photonics. © Photo: TU Berlin/Wolkenstein The laser is indispensable in the modern world, and a great future is predicted for it. What developments do you see from today's perspective, within the next 20–50 years? Lasers are key components for optics and electronics, which merge into the broad technological field of photonics. Because of efficiency, reliability and minimal size, diode lasers are of growing importance, which become available with almost any output power and for any wavelengths. Most lasers, several 100 million per year, are increasingly used for information storage on compact discs, CDs and DVDs, without most users noticing. Widespread use is expected for micro-projectors integrated in compact mobile phones, allowing display on room walls in television screen size. In the automotive industry, lasers will soon be used as lights. Diode lasers for materials processing supplant the traditional gas- and solid-state lasers. A potential application particularly What is the role of laser technology as an interface technology for the development of the industrial location Berlin-Brandenburg? Laser technology is used in many different areas and therefore has a strong influence on other technologies and clusters. In information and communication technology, lasers are used as transmitters for high speed data transmission over fiber optic networks, which – in the coming years – are to be brought close to houses and apartments of the user, representing another mass application of diode lasers. Those also find novel applications in engineering and microsystems technology, in health technologies and in measurement and sensor technology. Lasers are become more important in manufacture of solar cells and to store electrical energy in batteries. Without the laser, an advanced industry is no longer conceivable. What projects do you currently mainly work on at the Technical University? We focus on near-infrared lasers at 1.5 microns with higher power, to prepare for applications for effectively controlled laser surgery, to weld plastics, and for the detection of environmentally relevant greenhouse gases. We are also developing wave guides as well as silicon-based modulators, and we deal with the integration of dielectric multilayer systems on fiber end surfaces. The interview was conducted by Markus Wabersky and Arild Eichbaum 45
