Mirroring the development of research using optical wavelength lasers following their invention, we are currently witnessing rapid progress in studies of non-linear optical phenomena and applications at shorter and shorter wavelengths, as short wavelength FEL facilities reach maturity. Much of the recent work done at the Japanese SCSS test accelerator facility showcases non-linear phenomena. Here we present recent research exploiting the characteristics of the SCSS to observe superfluorescence, "Fano profile" wavelength filtering, and plasma up-conversion.
