An important step towards the realization of a VUV photon condensate has been achieved.
Noble gases under high pressure conditions play, among others, a role in astrophysics and plasma physics. They are also promising candidates for a thermalization medium for photons in the VUV regime. To study this in detail we have performed two-photon spectroscopy on Xenon at pressures up to nearly 100 bars.
