About KTH Laser Lab

KTH Laser Lab is a Research Infrastructure established at the Department Applied Physics, School of Engineering Sciences, KTH. The KTH Laser Lab facility comprises of well-established and well-equipped labs which perform research in quantum electronics, material science and expanding range of cross-disciplinary applications using unique tools and methods enabled by coherent light sources. The KTH Laser Lab has a mission of doing cutting edge research, providing advanced experimental skills for KTH students and supporting research and development needs of users throughout KTH, other Swedish educational and research organizations as well as industry. KTH Laser Lab maintains extensive national collaboration network, Laser-Lab Sweden, which allows our users to find the most efficient and qualified support in overcoming their research and development challenges.

Our capabilities

KTH Laser Lab (LLKTH) Research Infrastructure is a cluster of closely coordinated labs employing coherent light sources as a key tool for the basic and applied research. The experimental methods available at LLKTH, namely, time-resolved angle-resolved photoelectron spectroscopy (PI Oscar Tjernberg), ultrafast electron microscopy (PI Jonas Weissenrieder), time and spatially-resolved photoluminescence (PI Saulius Marcinkevicius), THz time-domain spectroscopy (PI Valdas Pasiskevicius) allow elucidation of ultrafast dynamics of charge carrier and lattice subsystems taking place in solid-state materials after optical excitation. These methods are extremely informative and useful in designing novel functional materials, including engineered nonlinear optical structures using ferroelectrics and semiconductors (PI Carlota Canalias). Such engineered nonlinear materials give novel functionality to nonlinear optical devices, therefore enabling novel application areas (PI Valdas Pasiskevicius). LLKTH maintains a unique facility for material processing (PI Michael Fokine) with deep experience in laser processing and 3D printing of different glasses and composites. These are employed for novel functional optical fibers and distributed sensing. LLKTH also maintains expertise in solid state and fiber laser design (PI Fredrik Laurell) which is used for realizing custom laser sources.
