Title: DETERMINATION OF DEGREE OF ANISOTROPY OF KTP CRYSTAL USING REFLECTANCE ANISOTROPY SPECTROSCOPY TECHNIQUE
Authors: Fekadu, Gashaw
Date Added: 6-Sep-2007
Abstract: Reflectance anisotropy spectroscopy (RAS) is a non-distractive optical probe of surfaces that is capable of operation within a wide range of environments. In this thesis by applying this optical technique it has been attempted to determine the degree of anisotropy of the biaxial Potassium Titanyl Phosphate (KTP) crystal with fractional error 0.165 %. In addition, the angle between the two optical axes of KTP crystal has been calculated with mean error 0.16 % for the case of acute angle and 0.17% mean error for obtuse angle. Furthermore, attempt was made to apply the method to natural basalt rock which is found from Ertal’ Ale eastern part of Ethiopia.
