We demonstrate that external noise can play a constructive role in a laser diode, inducing coherent mid-infrared radiation. Depending on noise intensity, the induced lasing can be either unimode or mulitimode. The coherence of the radiation in each mode reaches its maximum at an optimal noise intensity that differs depending on the mode. The phenomenon can therefore be classified as a multiple coherence resonance.
