The Laser Physics Laboratory is a so-called "Unité Mixte de Recherche" (UMR 7538) that is affiliated both to CNRS (National Center for Scientific Research - Institut de physique INP) and to University Paris 13.

Our research activity is mainly experimental in Physics and Optics. We study the physical interactions between matter and waves, either in fundamental Physics (atomic and molecular physics, spectroscopy…) or in more applied domains (organic light-emitting diodes, biomedical optics…), and often at the border of other area of science such as solid-state Physics, Chemistry, Biology or Nanosciences. These studies range from isolated atoms to living media, including simple or complex molecules, molecular clusters and materials. Waves are either a coherent light (laser) that is used as a tool for obtaining information about the medium studied, or a matter wave to be studied for itself.

The lab is divided into eight experimental teams (AF, COMETA, IOA, OCR, HOTES, AMIBES, LUMEN, OPTIMA) an it is composed of about seventy people (10 CNRS full-time researchers, 25 teachers, a technical staff of 15 people, about 20 PhD students and post-docs), plus several short-term trainees and foreign visitors.

Update team page Atomic spectroscopy at interfaces


Atomic spectroscopy at interfaces (ex OCR)

Topics of interest:



Atomic vapour Spectroscopy in the vicinity of an opics of interestAtomic vapour Spectroscopy in the vicinity of an interface:



Fundamental study of the properties of a free atom in the vicinity of an interface. Casimir-Polder interaction between an atom and a dielectric surface at non-zero temperature in the presence of surface polariton modes.

Sub-micron confinement of alkali atoms within the interstitial regions of an opal (quasi periodic three-dimensional structure of nanospheres), or within ultra-thin vapour cells.



Theoretical study of the interaction between an atom and an optical field with a complex spatial structure at a wavelength scale (Laguerre-Gauss beams, and nano-optics), notably the coupling with nearly forbidden atomic transitions (beyond the electric dipole approximation, and chiral properties).

Updated team page Dipolar quantom gases


Dipolar quantum gases (ex AF)

A new state of matter shows up when a dilute sample of atoms is cooled below a critical ultralow temperature. Then occurs a phenomenon known as the Bose-Einstein Condensation; this phase transition comes along with the building up of a macroscopic material system whose properties are non-classical, ie are dictated by the laws of quantum theory. We perform experiments to study these quantum gases with a special focus on their magnetic properties...
