Abstract :
The items discussed are: developments leading to the efficient nonlinear optical materials K3Li2Nb5O15and Ba2NaNb5O15; the relation of the stability to visible radiation shown by these materials to their, respectively, "completely filled" and "filled" tetragonal tungsten-bronze-like structures; a comparison of their physical properties to those of LiNbO3; the techniques and problems of growing optically satisfactory single crystals of Ba2NaNb5O15by pulling from the melt; processing required to obtain single domain sections and eliminate microtwinning; and the effects of excess Ba, Na, or Nb in the melt and the effects of substitutions by homologous cations.
