Features

Vector beams are very attractive because of their unique features such as small spot formation and strong longitudinal electric field near focus. We are developing a variety of generation methods of vector beams including Laguerre-Gaussian and Bessel-Gaussian beams and their higher order transverse modes. For instance, a smaller spot by approximately 30 % than that by a linearly polarized beam has been demonstrated and applied for nanoimaging.

Targeted Application(s)/Industry

Confocal scanning microscpy will benefit from vector beams as enhancement of spatial resolution. Otherwise, precision nano-processing will be possible. We are prepared to provide academic consultations to companies interested in our research.
