The Royal Institute of Technology is the largest technical university in Sweden which attracts approximately 30% of the Swedish research grants in natural and technical sciences. KTH promotes competitive, externally financed research. Moreover, the Institute is proactive in the field of technology and knowledge transfer between the academia and industry.

The laser physics group at the department of Applied Physics currently consists of 3 senior researchers (Prof. F. Laurell, Assoc. Prof. V. Pasiskevicius, Dr. C. Canalias) and 7 PhD students. From the year 2000 the group has graduated 15 doctoral students and typically supports 5 MSc diploma projects per year. The research is funded by the grants from private foundations, industry, national government agencies and European programmes. The group is also a founding member of a Joint Laboratory of Nonlinear Optics established through the private foundation, with the aim of promoting close collaboration between research groups in laser technology, nonlinear optics, quantum optics, spectroscopy and biophotonics.
The research activities of the group have been recognised in 2003 by the national Göran Gustaffson prize awarded by the Swedish Academy of Sciences.
The research conducted by the group covers topics in the fields of nonlinear optics, laser physics and material research specifically focussed on engineered nonlinear optical and Raman-active materials. In the field of lasers the research of the group has been investigating different laser materials for efficient diode-pumped operation, which were exploited for the generation of different wavelengths in the UV and blue-green parts of the spectrum by employing sum-frequency mixing processes. Nonlinear crystals structured using the technology developed in the group have been used to demonstrate ns, ps and fs OPOs, OPGs and OPAs over wide spectral ranges.
All three research areas covered by the group, namely lasers, nonlinear optics and nonlinear optical materials have attracted extensive international collaborations both within academic community and with commercial companies. This collaboration activity also was extended by participation of the group in international projects: FP5 LTR 26.522 FREMUX, FP6 NMP3-CT-2003-505580 DT-CRYS, both funded by EC and FABIOLA project funded by Western European Armaments Organization (WEAO). The research group maintains extensive collaborative ties with industrial partners, both national and international, resulting in substantial contract technology development and consulting component in overall project portfolio. Such practice is encouraged by the KTH policy and typically results in increased employment opportunities for graduated students.
