10 Cluster Report Optics and Photonics – Research and Industry | Laser Technology 2.1 Laser Technology – Cutting, Welding, and Measuring with Light “The laser has become a multipurpose tool used in manufacturing and is also a key component in medical, communications, and measurement technology. For more than 50 years, laser technology has been a focus of research and industry in Berlin Brandenburg.” Thomas Beck | Spokesperson Focus Area Laser Technology, Siemens AG, and Managing Director of Laserverbund Berlin-Brandenburg e. V. Today, lasers are essential tools that have found their way into many industrial sectors. Thanks to its special properties, laser light today serves as a tool for transmitting information, for highly accurate measurements, for surgical treatments, in automotive engineering, and in the production of computer chips, among many other applications. here covering many aspects of modern laser technology along the value chain from developing semiconductors for new laser materials to processes for using laser deposition welding on large turbine parts. World-Class Laser Research The Ferdinand-Braun-Institut, Leibniz-Institut fuer Hoechstfrequenztechnik (FBH) is one of the leading institutes in the field of optoelectronics and microwave technology. On the basis of III/V compound semiconductors, the FBH realises high-frequency components and circuits for communication and sensor technology. The institute develops powerful and highly brilliant diode lasers for materials processing, medical technology and precision metrology. One of FBH’s strengths lies in the field of high-power laser diodes. For partners and customers in research and industry, FBH develops tailor-made diode lasers for pumping solid state lasers for direct use in materials processing and medicine. www.fbh-berlin.de The latest laser technology is also used to manufacture eyeglass frames. @ Economic Development Agency Brandenburg (WFBB), S. Drosch The parameters of laser technology are constantly being improved. Scientists have penetrated into the attosecond range in time resolution. An attosecond is one-quintillionth of a second. With such unimaginably short pulses, fundamental chemical reactions can be monitored with the highest time resolution. In industry, stability and high performance guarantee high throughput. Kilowatt power and more than 99% availability are now commonplace. Cutting and welding in the automotive industry are just some of the applications where the laser has become the standard tool. The diversity of laser technology is also reflected in the Berlin Brandenburg region. Both world-renowned scientific institutes and a number of high-tech companies are based Laser wafers in sizes of 2, 3, and 4 inches © FBH/schurian.com

Cluster Report Optics and Photonics – Laser Technology 11 Together with the Quantum Optics and Metrology Working Group under Prof. Peters at HU Berlin, the FBH runs the Joint Laser Metrology Lab. The lab’s work in laser metrology includes microintegrated electro-optical modules, especially for use in remote locations or in space, interferometers for distance measurements between satellites or quantum-optical sensors such as optical atomic clocks and atomic interferometers. www.fbh-berlin.com/research/photonics/laser-metrology/joint-lab Pump module for high-energy short pulse laser systems with approx. 6 kW output power from the fibre © FBH/P. Immerz Diode laser on C-Mount © FBH/schurian.com Since 2017, the Leibniz Institute for Crystal Growth (IKZ) and FBH have been collaborating as part of the Federal Ministry of Education and Research (BMBF) funded EQuiLa project (researching and qualifying innovative laser materials and crystals) to establish the Center for Laser Materials-Crystals (ZLM-K) at the IKZ. The ZLM-K tests rare-earth- and transition-metal-doped oxidic and fluoride crystals structurally and spectroscopically for their usefulness in operating lasers. For the execution of simple laser experiments, diode lasers from the project partner FBH will also be used, where the Center for Laser Materials-Semiconductors ZLM-H is established within the EQuiLa project. In this way, a world-leading research environment is created in which laser demonstrators can be built using on-site amplifier media and pump sources. The Max Born Institute for Nonlinear Optics and Short Pulse Spectroscopy (MBI) also conducts top-level laser research at the Science and Technology Park Berlin Adlershof. MBI specialises in ultrashort and ultra-intensive laser pulses. On the one hand, the scientists there are working on new sources for such light pulses, on pulse shaping and pulse characterisation in a broad spectral range from the mid-infrared to the X-ray range. On the other hand, the researchers at the MBI use these possibilities to investigate ultra-fast, nonlinear phenomena in atoms, molecules, clusters and plasmas, as well as on surfaces and in solid bodies. Such combination of modern laser development and measurement technology paired with interdisciplinary applications impart the MBI its unique selling proposition and speciality for external users. www.mbi-berlin.de Such laser power packages are urgently needed, among other things, as a technological basis for the European large-scale project ELI (Extreme Light Infrastructure). ELI will become the world’s leading laser research infrastructure and is being built at three specialised facilities in the Czech Republic, Hungary, and Romania. This makes it the first ESFRI (European Strategy Forum on Research Infrastructures) project to be fully implemented in the new EU countries. The Deutsche Elektronen-Synchrotron DESY with its institutes in Hamburg and Zeuthen near Berlin is also a member of ELI. www.ikz-berlin.de/en/research1/center-for-laser-materials www.eli-laser.eu
