Abstract: Transmission Anisotropy Spectroscopy (TAS) or/and Reflection Anisotropy Spectroscopy (RAS) are a powerful non-destructive and sensitive optical probe of surface that is capable of operating with in a wide range of environments. In this thesis, by applying these optical techniques attempt was made to determine the degree of anisotropy of a biaxial Potassium Titanyl Phosphate (KTP) crystal and its value is of the order of 10−3 and 10−4 for reflection and transmission respectively. It is also seen that the absorption correction of KTP crystal is very small. Therefore the coupled techniques are also powerful for the determination of absorption loss of a transmitting probes. The methods used in this work can also be used in situ real-time measurements.
