At the laser threshold, the cavity switches from the strong coupling to the weak coupling regime. A gain-related transition, which appears while still observing polariton branches and, thus, with stable excitons, is observed below 240K. This shows that exciton scattering processes, typical of II-VI semiconductors, are involved in the gain process.","authors_text":"Bernard Gil (L2C), Christelle Brimont (L2C), F. Medard (LASMEA), F.
