“…The lifetime of the induced absorption was about several hours and depended on the temperature [14]. In [15]. In 2007 we investigated the spectral characteristics of the photo-induced absorption in the pure Bi 12 TiO 20 using pulse lasers and calculated the energy of the absorption centers [16].…”

A photorefractive Bi 12 TiO 20 (BTO) crystal is exposed with high intensity pulsed-laser beams 532 nm (the average intensity of the laser was 110 mW/cm 2 , the average intensity per pulse was 2 MW/cm 2 ), and the photo-induced dynamics of the absorption between 480 and 900 nm are studied and explained by two long-lived energy levels in the forbidden band. The relaxation times of the long-lived energy levels are experimentally found to be 10 4 and 10 5 s. The hysteresis character of the absorption coefficient is discussed.

“…A similar process was used by Tada et al [82] to produce BSO layers codoped with Al and Ca. LPE growth of bismuth titanate layers, undoped and doped with V, Cu, and Ca + Ga, on (100), (110), and (111) BGO and BSO substrates (20 × 30 × 2 mm) was described by Bondarev et al [84] and Kargin et al [87]. On (111) substrates, no single-crystal layers were obtained (Fig.…”

“…The processes for epitaxial growth of Bi 12 MO 20 plates and waveguides were described in [81][82][83][84][85][86][87]. Single-crystal BSO ribbons can be produced by the Stepanov method or EFG process [88][89][90].…”

The main processes for preparing bulk single crystals and films of photorefractive and piezoelectric Bi 12 M x O 20 ± δ (M = Group II-VIII elements) sillenite compounds are considered. Experimental data are summarized on the crystal growth of Bi 12 M x O 20 ± δ from the melt and under hydrothermal conditions, and the key morphological features of sillenites are analyzed. Various types of macroscopic growth defects in sillenite-type crystals are described, and their origin is discussed. The compositions of second-phase inclusions in undoped and doped (Group I-VIII elements) Bi 12 SiO 20 , Bi 12 GeO 20 , and Bi 12 TiO 20 single crystals are presented, and the main physicochemical properties of various Bi 12 M x O 20 ± δ crystals are summarized.

“…In 2002, Shandarov et al [13] investigated experimentally the photo-induced absorption in Bi 12 TiO 20 :Ca and suggested a three-level model, which is a special case of the two-center model. The lifetime of the induced absorption was about several hours and depended on the temperature [14] [15]. In 2007, we investigated the spectral characteristics of the photo-induced absorption in the pure Bi 12 TiO 20 using pulse lasers and calculated the energy of the absorption centers [16].…”

Methods for controlling of the laser-induced absorption in a BTO crystal by using of cw-laser radiation

et al. 2009

View full text Add to dashboard Cite

A photorefractive BTO crystal is exposed with cw-laser beams (430 mW/cm 2 at 514 nm), and the photoinduced absorption between 480 and 900 nm is studied. A method of controlling this absorption by low intensity laser radiation of "green" and "red" wavelengths is demonstrated. The physical mechanism can be explained by the redistribution of electrons on the long-lived energy levels into the forbidden band. Dynamical characteristics of the redistribution are estimated.
