This is a joint laboratory between KTH and Stockholm University for nonlinear optics, laser physics and surface science.

The laboratory was funded in 2003 by the Molecular Physics group at the Physics Department of SU and the Laser Physics group from the Applied Physics Department at KTH, as a result of generous funding primarily from the Knut and Alice Wallenberg Foundation. It has since then been further developed and now comprises two more groups; the Cell Physics group at KTH, and the Quantum Information and Quantum Optics group at SU, with a total of 60 researchers, including 27 Ph.D students.
