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 Ho3 in BaYb2F8 and 6 The characterization of the pumping dynamics and lasing properties of several Nd3 - doped crystals.
