Abstract : The objective of this thesis is to measure the transient nonlinear properties of thin film transition metal nitrites, specifically titanium nitride (TiN) and scandium nitride (ScN), using the beam deflection characterization technique. The thin films were made at the Air Force Research Lab by controllably unbalanced magnetron sputtering. Transition metal nitrides, specifically TiN, are used widely in industry because of their unique properties, including extreme hardness and high damage threshold. The properties of thin film transition metal nitrites are dependent on the chemical structure of the thin film, which can be heavily influenced by substrate and deposition method. This durability and tunability is an asset in applications such as sensor protection and all optical computing. Two substrates, sapphire (Al2O3) and magnesium oxide (MgO), were investigated. Two deposition parameters, 50V and 100V, were investigated. The substrate nor deposition parameter significantly affect the nonlinear optical properties.
