A low-power optical electron switch
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 1.2 mrad is achieved for an electron beam of 29 µrad 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 6 µs. Such a switch provides an alternative means to control electron beams, which may be useful in electron lithography and microscopy.
