A. Reichert et K. Betzler, INDUCED NONCOLINEAR FREQUENCY-DOUBLING - A NEW CHARACTERIZATION TECHNIQUE FOR ELECTROOPTIC CRYSTALS, Journal of applied physics, 79(5), 1996, pp. 2209-2212
Induced noncolinear frequency doubling (INCFD) is presented as a new c
haracterization technique for electro-optic crystals. Using the intera
ction of two noncolinear laser beams for the generation of second harm
onic light, the method yields a three-dimensional spatial resolution.
First experimental results of INCFD measurements on composition gradie
nts in lithium niobate and on the spatial orientations of 90 degrees-d
omain walls in potassium niobate are shown. (C) 1996 American Institut
