We experimentally investigated the temperature dependences of initial (before illumination)
value of absorption coefficient of Bi 12 TiO 20: Ca crystal for incoherent radiation of light …

Single crystals of Bi, TeO,, both undoped and doped with transition-metal-ion dopants, were
grown with high optical quality. Continuous-wave four-wave-mixing experiments on these …

An experimental and theoretical analysis of the two-wave mixing gain in Bi_12SiO_20 with
alternating electric fields applied is presented. The electromagnetic portion of the …

We report on the hole-electron competition in an undoped photorefractive B i 12 T i O 20
sillenite crystal in the presence of the photovoltaic effect. Experimental data gathered with …

LiNbO3 is a promising photorefractive material for many applications [1]. Phase holograms
formed in strip and planar waveguides may be used for phase conjugation, narrow-band …

The linear bulk photovoltaic effect (BPE) and photorefractive effect (PR) in La3Ga5SiO14
has interesting peculiarities, connected with symmetry of the crystal. Due to the symmetry the …

The dynamic behavior of the complementary space-charge gratings formed in a
Bi_12SiO_20 crystal through prolonged recording at 780 nm is used to determine a number …

Bi12SiO20 (BSO) crystals doped with Co, Ni, Cr, Mn, V and Fe have been studied. Classical
