We report on the first observation of superfluorescence (collective spontaneous emission) at an FEL, using the EUV free-electron laser and a high number density helium gas cell. We introduce superfluorescence as an example of quantum optics experiments which can be performed at the new generation of light sources, and discuss future prospects, including the extension to shorter wavelengths.
