“…7, the theoretical values of n y and n z are in accordance with the experimental data, and the tendency of the theoretical value of n x is same as that of the experimental data. The error between theoretical value and experimental data may relate to the photoelastic coefficient, which is difficult to measure, and only one piece of literature [36] is available. Even for some well-known optical crystals, such as LiNbO 3 , the measured photoelastic coefficients show significant difference [40].…”

A theoretical model is presented to explain the refractive index change in the ion-implanted KTP waveguide, which includes respective contributions of spontaneous polarization, molar polarization and molar volume, and photoelastic effect. Numerical calculations of refractive indices along different crystalline orientations (X, Y, and Z) as a function of the lattice damage level, determined by Rutherford back-scattering/channeling technique, are performed based on the results from a set of z-cut KTP crystals implanted by 300 keV He+ ions in doses ranging from 4×10(16) to 8×10(16) ions/cm2. The theoretical results show consistency with the experimental data. To our knowledge, this is the first model to comprehensively describe the ion-implanted KTP planar waveguide.

“…The linear electro-optic coefficients (r T ij and r S ij ) and principal relative permittivity (ε kk ) are measured by [1]. Some of photoelastic coefficients are given by [36]. Thus the values of the quadratic electro-optic coefficients and photoelastic coefficients can be calculated according to Eqs.…”

A measurement system for quantitative determination of both surface and bulk contributions to the photo-thermal absorption has been extended to anisotropic optical media. It bases upon a highly sensitive Hartmann-Shack wavefront sensor, accomplishing precise on-line monitoring of wavefront deformations of a collimated test beam transmitted perpendicularly through the laser-irradiated side of a cuboid sample. Caused by the temperature dependence of the refractive index as well as thermal expansion, the initially plane wavefront of the test beam is distorted. Sign and magnitude depend on index change and expansion. By comparison with thermal theory, a calibration of the measurement is possible, yielding a quantitative absolute measure of bulk and surface absorption losses from the transient wavefront distortion. Results for KTP and BBO single crystals are presented.
