Abstract

Time and space-with high resolution: Time-resolved second harmonic generation (TRSHG) signals produced via photoexcitation of carriers in ZnSe exhibit different relaxation rates depending upon carrier proximity to an interface; these rates can be controlled via one-versus two-photon excitation. When combined with near-field scanning optical microscopy (NSOM; see graphic), which can provide
