Abstract

Optical features of point defects photoluminescence in LiF crystals, irradiated by soft X-ray pulses of the Free Electron Laser with wavelengths of 17.2 – 61.5 nm, were measured. We found that peak of photoluminescence spectra lies near of 530 nm and are associated with emission of F3+ centers. Our results suggest that redistribution of photoluminescence peak intensity from the red to the green part of the spectra is associated with a shortening of the applied laser pulses down to pico - or femtosecond durations. Dependence of peak intensity of photoluminescence spectra from the soft X-ray irradiation fluence was measured and the absence of quenching phenomena, even at relatively high fluencies was found, which is very important for wide applications of LiF crystal X-ray imaging detectors.

(a) Typical plot of PL spectra dependence from pumping excitation wavelengths, obtained for blank and irradiated LiF crystals by 61.5 nm SASE-FEL beams. (b) Spectra of PL for blank and exposed LiF crystals, which were excited by λ1 = 270 and λ2 = 450 nm.

(a) Normalized PL spectra of LiF irradiated by SASE – FEL beam with different wavelengths. (b) Comparison of normalized PL spectra of LiF crystals irradiated by 61.5 nm SASE – FEL and by optical laser pulses with different durations. In all cases the LiF crystals were excited by 450 nm pulses.

Dependence of PL peak intensities (λ = 530 nm) from the accumulated fluence of SASE-FEL beam irradiation of LiF crystal at the wavelengths of 61.5 nm.

The soft X-ray coherent diffraction patterns, measured at ~26 mm distance from the Ni mesh. The square mesh with 36.5 μm size of wire and period of 360 μm was irradiated by SASE-FEL beam with wavelength of 61.5 nm by one (a) and by 30 laser shots (b). Good reproducibility of SASE-FEL beam optical properties from shot to shot is clearly seen from the high contrast of diffraction patterns in the last case. (c) The PL spectra peak intensities (λ = 530 nm) dependences on the fluence of SASE-FEL beam irradiation of LiF crystal at the wavelengths of 61.5 nm were obtained by diffraction and by direct measurements.
