Optical characterization of microcrystals
Abstract
A new method to optical characterization of microcrystals is described and illustrated with experimental results. Techniques for characterizing the linear and nonlinear parameters of new materials at early stages of crystal growth have been developed. The linear indices of refraction and their dispersion are determined using combined methods of spindle stage microscopy and refractometry. This method has been extended to measurements at nonvisible wavelengths. An SHG apparatus of novel design is used to evaluate the overall nonlinearity. Both methods are used to study materials with single crystal domains as small as 50 microns.
