CASTILLO-TORRES, J et al. Self-focusing in chromium-doped potassium niobate single ceramic crystal. Rev. mex. fis. [online]. 2006, vol.52, n.6, pp.540-545. ISSN 0035-001X.

The self-focusing and nonlinear optical absorption in a chromium-doped potassium niobate single ceramic crystal have been investigated. The third-order electric susceptibility χ⁽³⁾ at continuous 532 nm radiation is estimated based on a band transport model describing photorefractive properties for this electro-optic material. An anisotropic behavior on its nonlinear optical absorption properties has also been observed due to the presence of chromium ions.

Keywords : Self-focusing; nonlinear electric susceptibility.
