OPTICAL SECOND-HARMONIC RESPONSE OF AN AXIALLY-SYMMETRIC MEDIUM UNDER RADIALLY POLARIZED EXCITATION
We simulated optical second harmonic response, both surface and bulk, of axially symmetric media excited by tightly focused radially polarized fundamental beams. The modeling showed a highly localized character of second harmonic generation. We estimated decrease of overall second harmonic signal...
