Tm3+:GdAl3(BO3)4 crystals were grown successfully from K2Mo3O10-B2O3 solvent by using the top seeded solution growth method. The absorption spectra for both σ and π polarizations were presented. The Judd-Ofelt (J-O) intensity parameters were found to be Ω2=4.54×10-20 cm2, Ω4=2.25×10-20 cm2, and Ω6=3.39×10-20 cm2. The spectroscopic parameters of this crystal such as the oscillator strengths, radiative transition probabilities, radiative lifetime as well as the branching ratios were calculated. Unpolarized and polarized emission spectra were obtained under the excitations of 468 and 797 nm, respectively. This crystal may be preferable for GaAlAs laser pumping. [ABSTRACT FROM AUTHOR]

The dynamics of polarization switching have been investigated over extremely broad time (10-8< t< 10² s) and field ranges for (001) c, (110) c, and (111) c-oriented Pb (Zn 1/3 Nb 2/3) O 3-4.5%PbTiO 3 crystals. The results demonstrate the presence of broad relaxation time distributions that can extend over a decade (s) in orders of magnitude in time, and which sharpen significantly with increasing field. The polarization transients have been fit to stretched exponential functions, which are typical of disordered systems. [ABSTRACT FROM AUTHOR]

A magnetoelectric laminate composite consisting of magnetostrictive Terfenol-D (Tb1–xDyxFe2–y) and piezoelectric Pb(Zr,Ti)O3 layers has an extremely high voltage gain effect of ≈300 at its resonant state, offering potential for high-voltage miniature transformer applications.
