To characterize the statistical fluctuations of the laser light, an additive white noise (representing spontaneous emission source) is included in the conventional laser theory, that adds phase and amplitude fluctuations to the optical field. However, the conventional laser models used in the previous analysis1 only contains cubic nonlinearities and orthogonality of the laser modes. Recently, the cubic model of the statistical properties of light from a laser at steady-state have been developed to take into account the nonorthogonal nature of the laser modes2.
