چکیده
We have measured the thermal expansion and the temperature dependence of z and y components of the refractive index for KTiOPO4 and KTiOAsO4, in the wavelength range 532-1585 nm and temperature range 25-200 degrees C, using an interferometric technique. The measurements were used to derive temperature-dependent Sellmeier equations for the two materials. These equations predict with good agreement the temperature dependence of quasi-phase-matched nonlinear frequency converters.

Wavelength variation of the second-order nonlinear coefficients of KNbO3, KTiOPO4, KTiOAsO4, LiNbO3, LiIO3, b-BaB2O4, KH2PO4, and LiB3O5 crystals: a test of Miller wavelength scaling
We measure second-order nonlinear coefficients using optical parametric amplification and second-harmonic generation over a range of wavelengths for the crystals KNbO3, KTiOPO4, KTiOAsO4, LiNbO3, LiIO3, b-BaB2O4, KH2PO4, and LiB3O5. Combining our new measurements with previously reported values, we compare the wavelength variation of individual dijk’s with Miller scaling, and we conclude that M...
متن کاملFemtosecond Z-scan measurements of nonlinear refraction in nonlinear optical crystals
We report an investigation of third-order optical nonlinearities in several nonlinear optical crystals using the Z-scan technique with femtosecond laser pulses at 780 nm wavelength. The crystals studied include LiNbO3:MgO, KTiOAsO4, KTiOPO4, b-BaB2O4 and LiB3O5, which are extensively used for ultrashort-pulse second-harmonic generation and optical parametric oscillation. The nonlinear refractiv...
متن کاملX-ray investigation of lateral hetero-structures of inversion domains in LiNbO3, KTiOPO4 and KTiOAsO4
In this paper periodically domain-inverted (PDI) ferroelectric crystals are studied using high-resolution X-ray diffraction. Rocking curves and reciprocal-space maps of the principal symmetric Bragg reflections in LiNbO3 (LN) (Λ = 5 µm), KTiOPO4 (KTP) (Λ = 9 µm) and KTiOAsO4 (KTA) (Λ = 39 µm) are presented. For all the samples strong satellite reflections were observed as a consequence of the P...

متن کاملPolarization reversal and domain grating in flux-grown KTiOPO4 crystals with variable potassium stoichiometry
A significant decrease is observed in the dielectric dispersion, conductivity, coercive and internal fields of KTiOPO4 crystals grown with relatively high potassium concentration in the flux. A periodic domain structure with a period of 24.7 mm was fabricated on a 10 mm long crystal by electric field poling. Whereas standard flux-grown KTiOPO4 crystals can be periodically poled only at low temp...
