    I imagine that lithography for integrated circuits would be an application, assuming you could make an appropriate photo-resist. The shorter the wavelength, the smaller the possible feature size. Current lithography relies on constructive and destructive interference between wavelengths to create super small features.

      As far as “light” it’s already capped out, then. Going shorter there’s only x-ray and then Gamma ray. Gamma ray lithography sounds bad-ass and dangerous.

        Gamma rays have so much energy that they are basically emitted only by nuclear processes, as far as I know.
