INVESTIGATIONS OF WATER SOLUTIONS OF EUROPIUM CHELATES AS LASER MATERIALS
Abstract
Because heavy water should be a superior liquid laser solvent, studies of various systems soluble in heavy water have been emphasized. In order to obtain materials which can be efficiently optically pumped in large volumes of practicable dimensions, two different approaches have been employed. The first is to form mixed ligand complexes in solution. This modifies the absorption band of the chelate directly. Two systems of this type are described. The second approach is that of utilizing intermolecular energy transfer in solution. We have demonstrated, for the first time, intermolecular energy transfer in heavy water solutions. Two systems of this type are described. Studies of systems soluble in organic solvents have aided in the development of systems in heavy water. Laser operation has been achieved with three of these new europium chelates in acetonitrile. The effects of scattering on laser performance are shown to be large for these systems soluble in organic solvents.
