摘要	This paper presents an approach to the intracavity interaction of electromagnetic waves with anharmonic lattice vibrations of ionic crystals. The nonlinear lattice dynamics and an expression for the nonlinear polarization are derived in terms of optical phonon modes. In the rotating-wave approximation the total coherent Hamiltonian of the system is derived. Using the corresponding equation of steady states, the increasing absorption optical bistability (IAOB), as a nonlinear effect, is demonstrated. The results show that optical nonlinearities due to the interaction of photons with various elementary excitations of bosonic type such as phonons and excitons may be the origin of IAOB, which is consistent with our previous works.
