From a study of the melting diagram KPO 3 —KNdP 4 O 12 optimum conditions are derived for the growth of KNd(PO 3 ) 4 single crystals by the flux method. The absorption spectrum of KNd(PO 3 ) 4 was measured between 320 and 1000 nm at room temperature. The three J UDD ‐O FELT parameters Ω λ were determined by numcerical methods and compared to the data for NdP 5 O 14 . A correlation has been attempted between the Ω 2 parameter and the site symmetry of Nd 3+ in Nd‐containing laser crystals. The calculated fluorescence branching coefficients from the 4 F 3/2 level are in good agreement with the epxerimental data.
