Abstract: The parametric excitation of the low-frequency overtone in GaSe crystal by a biharmonic optical field is shown to lead to bistability of both the crystal refractive index and the optical field generated in the four-wave-mixing process. The effect appears to be much stronger in layered crystals than in crystals of higher symmetry.
