摘要：

We measure the efficiency and phase of picosecond phase conjugate reflectivity by degenerate four-wave mixing for colloidal gold suspended in water and in glass. Evidence is found for extremely high χ(3) for the gold particles. However, the efficiency has a power dependence which is not increasing quadratically with pump energy. Small-scale lensing effects become significant at high pump energies. Additionally, both the glass-based and the water-based colloids show a visible "permanent" bleaching effect after absorbing only a few pulses of GW/cm2 intensity. © 1990 American Chemical Society.
