| Research Abstract |
The aim of this research was to establish the fundamental technology for the novel optical trapping of opaque particles. First, single-transverse higher-order radially polarized beams were selectively generated from a Nd:YAG laser cavity by using a reflectivity-modified polarization-selective photonic crystal mirror. Second, the longitudinal electric field of a tightly focused radially polarized beam was experimentally demonstrated by means of second harmonic generation.
