Tunable Solid State Lasers Based on Molecular Ions
Abstract
The main objective of this program was to investigate the possibility of developing tunable solid state lasers based on complexes of Transition Metal Ions in their highest valency state or equivalently do configuration. This is a class of materials, often referred to as phosphors with strong absorption bands in the UV, and thus well suited for excimer laser pumping. We have found that, contrary to initial arguments, Excited State Absorption processes are very strong and overlapping the emission spectrum. Indications are that octahedral complexes, rather than tetrehedral may have a greater chance, especially in inorganic glasses. Additionally photochromic effects in BGO are reported and a study of non-radiative processes in broad band emitters, the later showing the inadequacy of present theoretical approach.
