the enhancement of a laser's quantum noise and linewidth when its cavity modes are nonorthogonal, as in gain-guided or unstable resonators.

In laser physics, Petermann excess noise factor refers to the enhancement of a laser's quantum noise and linewidth when its cavity modes are nonorthogonal, as in gain-guided or unstable resonators. This meaning comes from Petermann (1979) in IEEE Journal of Quantum Electronics.[1]
