Manufacturing technology for three-dimensional nanostructures has been required. In this study, we proposed a laser additive processing method in vapor phase aiming for fabricating three-dimension structures with nanoscale resolution, by utilizing optical trapping potential to confine particles in a range smaller than diffraction limit of laser beam. In this paper, we developed the equipment for basic experiments of which the intention is to investigate the relation between the shape of optical trapping potential and the performance of particles confinement. We would use Bessel beam, which propagates without changing its intensity distribution in a certain length, for particles confinement in this basic study. We conducted microparticles confinement experiment in liquid phase as a basic examination.
