AbstractExperimental measurements of the second order susceptibilities for the second harmonic generation are reported for YAl3(BO3)4 (YAB) single crystals for the two principal tensor components xyz and yyy. First principle's calculation of the linear and
nonlinear optical susceptibilities for Yttrium Aluminum Borate YAl3(BO3)4 (YAB) crystal have been carried out within a framework of the full-potential linear augmented plane wave (FP-LAPW) method.
Our calculations show a large anisotropy of the linear and nonlinear optical susceptibilities. The observed dependences of
the second order susceptibilities for the static frequency limit and for the frequency may be a consequence of different contribution
of electron-phonon interactions. The imaginary parts of the second order SHG susceptibility PACS Codes: 71.15. Mb; 71.15.-m |
