We demonstrate a graphene based saturable absorber mode-locked Nd:YVO4 solid-state laser, generating ∼14nJ pulses with ∼1W average output power. This shows the potential for high-power pulse generation.
In this paper, mono-color and full-color FED prototypes of various sizes and resolutions have been fabricated. Video display has been demonstrated. The results show that the newly developed screen-printed CNT composite cathode is suitable for large area high resolution display application.
Summary form only given. The goal of producing THz radiation from miniature electron beam devices has refocused interest in orotrons. Here we consider planar orotrons driven by electron beams produced by carbon nanotube cathodes. The efficiency of these devices improves with increasing current density. However, with increasing current density, self-fields become more important. Here, the theory of...
