Interaction of laser radiation with matter
Generation of the highest possible concentrations of the F2 color centers in lithium fluoride crystals by a laser-plasma source of soft x-ray radiation
Abstract:
A new method was developed for coloration of crystals by low-energy soft x-ray photons. Crystals of LiF with the F2 color centers in concentrations up to 1019 cm – 3 and a colored layer 4 μm thick were obtained.
