Three different regimes of laser emission are observed corresponding respectively to Mollow, Raman and Four Wave Mixing mechanisms. We measure an output power of up to 300 $μ$W and present the main properties of these different lasers in each regime.Atomic PhysicsDisordered Systems and Neural NetworksOpticstext
