CHROMIUM-NEODYMIUM ENERGY TRANSFER IN YAP

P. Nelson , A. Brenier , C. Pedrini , G. Boulon , J. Mares

Yttrium aluminum perovskite (YAP) co-doped with Cr3+ and Nd3+ is of interest in laser applications because the chromium-neodymium energy transfer is more efficient in YAP than in YAG. Investigation of the energy transfer from the chromium R lines and pair states in the wavelength range 720-740 nm to the Nd3+ upper laser level shows that neither individual Cr3+ ions nor C3+-Cr3+ pairs are important energy donors in YAP. The results are consistent with a model of nonuniform distribution of donors.
