Laser Spectroscopy Characterization of Materials for Frequency Agile Solid State Laser Systems

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.
