Abstract

Extensive spectroscopy, interferometry, polarimetry, X-ray topography, phase matching homogeneity and laser-induced damage measurements were performed on full-scale and/or sub-scale nonlinear crystals. Most optical imperfections were related to one of the features of the growing crystal: dislocation bundles generated during seed regeneration or inclusion incorporation; differences in impurity incorporation across boundaries separating the {100} and {101} crystal sectors; differences in impurity incorporation across boundaries separating the three vicinal sectors of dislocation growth hillocks on the {101} face; and inclusion of sub-micron absorbing particles or defect clusters. Thermal and laser annealing have a dramatic effect on damage thresholds.
