Refractive indices for the crystals KDP, ADP, RDP, KDA, ADA, RDA, CDA, KDP:Rb, and most of their deuterated forms were measured from 404 to 1064 nm with ±3 × 10−5 accuracy. Numerical fits to standard and modified versions of the double-resonance Sellmeier formula were made, permitting interpolation of the index data consistent with the measurement accuracy. Samples of KDP from different crystal growers had slightly different (~3 × 10−4) refractive indices, which correlated with deviations in the lattice parameters.
