CHELATE WATER SOLUTION LASERS
Final technical summary rept. for 1 Jul-31 Dec 1964

Heavy water is considered as a liquid laser solvent. Its unique combination of good optical homogeneity, low absorption at the laser output frequency and low viscosity make it very attractive for proposed high radiance liquid laser systems. The heavy water soluble rare-earth chelate research at the Westinghouse Research Laboratories both before the start and during the present contract is described. Chelates having adequate solubility, high quantum efficiency and improved absorption bands were developed. Unfortunately photodecomposition of these chelates has prevented laser action from being achieved. It is expected, however, that this problem can be overcome. The work with europium benzoyltrifluoroacetonate both before and after the end of the present contract is described. To date, laser action has been achieved in 10 salts of this compound in acetonitrile near room temperature. Output beam divergence, spectral narrowing and thresholds for laser action are discussed.
