The Atomic Physics division pursues research within a broad spectrum of basic and applied atomic and molecular physics. Laser based techniques are mostly employed. The most powerful laser system in the Nordic countries, featuring 40 terawatt pulses, is found in the High power laser facility, and is used for acceleration of electrons and protons, and for the generation of soft X-ray laser radiation as well as broadband hard X-rays. 

A further main line of research is the generation, characterization and utilization of high harmonics, now from a system with high repetition rate. Attosecond pulses are generated by phase locking, and the new field of attophysics is explored in a vigorous research programme. Intense, short laser pulses are also combined with synchrotron radiation in a further programme, where solids are studied with time-resolved X-ray diffraction. 

Laser spectroscopic studies of radiative processes in free atoms and ions are pursued in close connection to astrophysics. A research programme in quantum optics and quantum information utilizes laser spectroscopic techniques in crystalline materials. The division also pursues extensive research towards applications within the environmental and medical fields. Laser radar techniques and diode laser spectroscopy are being developed for the study of air pollutant but also for status assessment of historical monument facades. 

Research in laser medicine starts with basic studies of light propagation in scattering media, with applications to early tumour detection, gas diagnostics in human cavities, and the treatment of tumours with photodynamic methods. The Division is strongly involved in the Lund Laser Centre, the administration of which it also handles.
