Abstract: A crystal of KTax Nb1-x O3, where x lies between 0.2 and 0.8 is produced by said crystal growth from a melt at 1250 DEG C in an oxygen containing atmosphere. Initial ingredients may be in the form of oxides or carbmates, and small quantities of Sn, Si, Ge and Ti may be added as dopants. Care is taken to minimise the presence of Ca, Cl, F, Sr, Ba, Na and Li.
Abstract translation: 通过在1250℃的熔体中在含氧气氛中的晶体生长，产生了X在0.2和0.8之间的KTax Nb1-x O3晶体。 初始成分可以是氧化物或碳酸镁的形式，并且可以添加少量的Sn，Si，Ge和Ti作为掺杂剂。 注意使Ca，Cl，F，Sr，Ba，Na和Li的存在最小化。

Abstract: Adjustable color in the visible spectrum results from use of a gallium arsenide infrared emitting diode provided with a coating of a composition having at least one each of two different anions in some unit cells. The composition exemplified by a variety of oxyhalides contain the cation pair Yb3 -Er3 , Yb3 -Ho3 and mixtures thereof.

Abstract: Acousto-optic devices dependent for their operation on lead molybdate (PbMoO4) and related compounds show efficiencies comparable to that of devices made from alpha-iodic acid and superior to that of devices constructed of earlier materials such as lithium niobate. Optical deflectors useful in modulators, switches and correlators are described.
