ultralumina is commercializing special optical fibers and light sources for the deep and vacuum ultraviolet.
The spin-off ultralumina is hosted at the Max Planck Institute for the Science of Light (MPL) in Erlangen, Germany.
Power spectral density (log scale) when pumping with a 300 fs, 10 uJ, 1030 nm laser at a repetition rate of 1 MHz (gas parameters: 25 bar Argon).
Tunability of the UV emission peak (linear scale) when applying different Argon pressures. For other working gases (e.g. Kr, Xe, Ne) the emission peak shifts.
A new generation of versatile and efficient gas-based light sources, which are tunable from the vacuum ultraviolet to the near infrared, and of versatile and efficient pulse compression devices is emerging.
[...] such a system would provide a unique source for metrology and spectroscopy.
