Degenerate four-wave-mixing measurements have been performed on a wide variety of Nd{sup 3+}-doped oxide and fluoride glasses and crystals. Crossed beams from a cw argon-ion laser were used to excite the Nd{sup 3+} ions directly and establish population gratings. Absolute measurements of the signal strengths were made, and their magnitudes were found to be sensitively influenced by the composition of the host. A theoretical model was developed to interpret the results, and it was found that the dominant contribution to the signal is associated with the difference in polarizability of the Nd{sup 3+} ions in the metastable state versus the ground state. The magnitude of the observed change in the polarizability indicates that the 4{ital f}{r arrow}5{ital d} transitions are responsible for this effect, and as a result, the value of the {l angle}4{ital f}{vert bar}{ital r}{vert bar}5{ital d}{r angle} radial integral sensitively affects the calculated polarizability change.
