CEP-stable Tunable THz-Emission Originating from Laser-Waveform-Controlled Sub-Cycle Plasma-Electron Bursts [PDF]
, 2015 We study THz-emission from a plasma driven by an incommensurate-frequency two-colour laser field. A semi-classical transient electron current model is derived from a fully quantum-mechanical description of the emission process in terms of sub-cycle field-

Electron Holography by Field Emission Electron Microscope
Nihon Kessho Gakkaishi, 1980 A 100 kV field emission electron microscope has been developed which has lattice resolution of 0.62 A. Electron holography was put to practical use utilizing the high coherence of this electron beam. The coherence of the electron beam was demonstrated by photographing 3, 000 bi-prism interference fringes, which is an order of magnitude greater than the
