Laser-induced plasma emits VUV radiation. Therefore, analysis of the VUV radiation gives access directly to information of the plasma parameters such as density and electron temperature.
Due to a coherent process, when solid samples, gas or plasma are illuminated by a pulsed laser, the sample emits the high harmonics of the generation beam and could be used as a discontinued emission light source in the VUV domain.
A VUV monochromator can provide a precisely selected wavelength down to the Soft X-Ray, and can thus act as a tunable filter or light source with appropriate accessories
Multilayer structures analysis, improvement of reflectivity of mirrors (optics of a Synchrotron) or radiation damage studies are some of the domains of investigations of “in vacuum” reflectivity
By irradiating a material with a beam of X-Rays while simultaneously measuring the kinetic energy and number of electrons that escape from the top 1 to 10 nm of the material, information of the elements, such as elemental composition, chemical state, and electronic state can be obtained.
VUV fluorimeter
Phosphors or scintillators based on organic or inorganic crystal or noble gases can be characterized using such a technique. Their Lifetime measurements are another domain under investigation these past years.
VUV light can be used to stimulate fluorescent dyes to highlight defects in materials
