Abstract : This research involves the use of laser spectroscopy techniques to investigate materials which include laser crystals such as Cr3+ -doped alexandrite, emerald, garnets, and glass ceramics as well as Nd3+ -doped garnets and germinates and Ho3+ -doped fluorides. In addition, photorefractive processes were studied in potassium niobate crystals and in rare earth doped glasses. Some of the results of major importance from this work are: (1) The characterization of the properties of laser-induced gratings in glasses; (2) The elucidation of the effects of dopant ions on the photorefractive response of potassium niobate; (3) The observation of a new type of picosecond nonlinear optical response in potassium niobate associated with scattering from a Nb hopping mode; (4) The characterization of the properties of energy migration and radiationless relaxation processes in Cr3+ doped laser crystals; (5) The characterization of the pumping dynamics and lasing properties of Ho+3 in BaYb2F8; and (6) The characterization of the pumping dynamics and lasing properties of several Nd3+ - doped crystals.
