Paper Abstract

The LiKSO4 (LPS) and (NH4)2BeF4 (AFB) crystals belong to ferroelectrics with incommensurate phase and birefringence inversion. Birefringence inversion point (lambda) 0 in LPS crystals was observed in spectral ranges 240...360 nm within 180...430 K. Two regions of (Delta) ni sign change of AFB crystals were observed (76 K and 312 K) for spectral range 400...1000 nm. The purpose of the paper is to investigate the influence of ancienting, annealing and x-ray irradiation on temperature and spectral dependences of birefringence (isotropic point) of LPS and AFB crystals.
