The laboratory, managed successively by Ph. Durand, J.P. Malrieu, J.P. Daudey, N. Halberstadt et F. Spiegelman (from 2007), knew a relatively important growth until include approximately 35 permanent employees in 2006. Some important landmarks marked the life of the laboratory. Let us mention the action of the laboratory to make grow in Toulouse a Fundamental structure of Physics and Chemistry. This action has entailed the arrival of several teams, molecular physicists and opticians of lasers who have created the Laboratoire Collisions Agrégats Réactivité (LCAR) in 1990, and also theoretical physicists who have created the LPT Laboratoire de Physique Théorique in 2003.
Its around these laboratories that IRSAMC (The Institute of Research on Complex Atomic and Molecular Systems) has been created.
