— This paper applies results on the robust stability of nonlinear quantum systems to a system consisting an optic al cavity containing a saturated Kerr medium. The system is characterized by a Hamiltonian operator which contains a nonquadratic term involving a quartic function of the annihila tion and creation operators. A saturated version of the Kerr nonlinearity leads to a sector bounded nonlinearity which enables a quantum small gain theorem to be applied to this system in order to analyze its stability. Also, a non-quadratic versi on of a quantum Popov stability criterion is presented and applied to analyze the stability of this system.
