摘要：

Using degenerate four-wave mixing in a LiNbO3:Fe 0.04 wt.% crystal we have observed substantial enhancement of light scattered by crystal surface irregularities. It is believed that the enhancement originates in the phase conjugation process. We have found that the signal detected in a scanning near-field optical microscope can be more than ten times higher from a subwavelength sized surface bump than from a flat surface. We have attributed this enhancement to multiple phase conjugation of scattered field components which are evanescent in air but propagating in the crystal.
