Abstract

An electron beam is deflected when it passes over a silicon nitride surface, if the surface is illuminated by a low-power continuous-wave diode laser. A deflection angle of up-to 1.2mrad1.2 \,\textrm{mrad} is achieved for an electron beam of 29μrad29 \,\mu\textrm{rad} divergence. A mechanical beam-stop is used to demonstrate that the effect can act as an optical electron switch with a rise and fall time of 6μs6 \,\mu\textrm{s}. Such a switch provides an alternative means to control electron beams, which may be useful in electron lithography and microscopy.
