Methodology for optical studies of nonlinear crystals: application to the isomorph family , , and
TL;DR: In this paper, the authors developed a methodology for the measurement of quadratic nonlinear optical properties of crystals, mainly based on the use of the spherical geometry which allows, with only one crystal, accurate measurements of the phase-matching directions and the associated angular acceptances, double-refraction angles and effective coefficients.
Journal ArticleDOI
Phase-matching directions and refined Sellmeier equations of the monoclinic acentric crystal BaGa 4 Se 7
Elodie Boursier,Patricia Segonds,Bertrand Ménaert,Valeriy Badikov,Vladimir Panyutin,Dmitrii Badikov,Valentin Petrov,Benoît Boulanger +7 more
TL;DR: The phase-matching directions of second-harmonic and difference frequency generation in the principal planes of the biaxial BaGa4Se7 (BGSe) crystal are measured using the sphere method to refine the Sellmeier equations of the three principal refractive indices of BGSe and to calculate the tuning curves for infrared optical parametric generation.
Journal ArticleDOI
High temperature piezoelectric properties of flux-grown α-GeO 2 single crystal
Philippe Papet,Micka Bah,Abel Haidoux,Benoit Ruffle,Bertrand Ménaert,Alexandra Peña,Jérôme Debray,Pascale Armand +7 more
TL;DR: The temperature dependence of the piezoelectric properties of trigonal -GeO2 single-crystals obtained by the high-temperature flux method was measured by the resonance technique of the electrical impedance in the 20°C-600°C range as mentioned in this paper.
Journal ArticleDOI
Intrinsic ionic screening of the ferroelectric polarization of KTP revealed by second-harmonic generation microscopy
Mario Maglione,Anand Theerthan,Vincent Rodriguez,Alexandra Peña,Carlota Canalias,Bertrand Ménaert,Benoît Boulanger +6 more
TL;DR: In this paper, the Coulomb interaction between the mobile free charges and the fixed lattice dipoles was investigated using SHG microscopy, and it was shown that mobile charges and lattice polarization interact in ferroelectric materials.
Journal ArticleDOI
Thermal stability of ferroelectric domain gratings in Rb-doped KTP
Gustav Lindgren,Alexandra Peña,Alexandra Peña,Andrius Zukauskas,Charlotte Liljestrand,Bertrand Ménaert,Bertrand Ménaert,Benoît. Boulanger,Carlota Canalias +8 more
TL;DR: In this paper, the authors studied the thermal stability of domain walls in periodically poled Rb-doped KTP crystals, and showed that the domain wall motion is highly anisotropic along the a- and b- crystallographic axes.
