Results
Absorption spectra of two-photon transitions in xenon, driven non-degenerately with VUV light and an auxiliary light field, and recorded by easyLIGHT VUV with an intensified CCD camera. (b) Different wavelengths of the auxiliary light field (480-510nm) result in spectrally shifted spectra. (c) The wavenumber sum of the two driving light fields.

Experimental high harmonic spectra reflected from monocrystalline silicon with linear polarization of the driving pulse along [100] (black curves) and [110] (red curves) crystallographic directions measured with easyLIGHT VUV. The central photon energies of the driving pulses are 0.6 eV (wavelength of 2000 nm).

Sulfur detection by Laser Induced Breakdown Spectroscopy (LIBS) on lunar-analog samples. The aim is to study the potential of VUV-LIBS on a mission to Mars. The results with easyLIGHT indicate improved detection capabilities for sulfur as compared to LIBS in standard spectral ranges. Limits of detection for S are estimated at 0.5at%.
