| Outline of Final Research Achievements |
This research aimed to establish a basic technology to transfer the wavefront from light wave to electron wave by using wavefront control techniques developed in the field of light. The wavefront transfer from light wave to electron wave was conducted by a hologram fabricated by light beams, for which a new technique was developed to precisely control the wavefront and intensity distributions of light wave. These techniques were applied to laser micro-processing of a hologram used for the generation of an electron vortex. Because this hologram contains a phase modulation, which is a unique feature of this hologram, improvement of the conversion efficiency to electron wave is expected.
