Phase-mismatched optical second-harmonic generation in a low-loss external enhancement cavity is used to generate an effective third-order nonlinearity for continuous-wave laser radiation. The threshold for optical bistability is calculated. The cascading effect is demonstrated by detecting bistability of the line shape of a low-loss monolithic MgO:LiNbO3 resonator pumped by a Nd:YAG laser. The simplicity of cascaded resonators makes the method particularly promising for quantum optics.
