Abstract: Poling of ferroelectric tungsten bronze-like crystalline material in which the cation sites are substantially filled is expedited by electrolysis at temperatures in excess of the ferroelectric Curie temperature for periods of the order of one hour for bodies one centimeter in length. Electrolysis is carried out in an atmosphere which will yield positive ions such as H , D and Li which migrate through the body during processing.

Abstract: Uniaxial magnetic anisotropy in supposedly isotropic garnet compositions is found to be related to growth direction of the crystal. Wafers cut from crystalline sections, selected such that growth direction is consistent with formation of but a single 211 face, are usefully incorporated in bubble domain devices-a class of magnetic devices in which information is represented by enclosed single domain regions of polarity opposite to that of immediately surrounding material.

Abstract: Optical devices depending for their function upon the incorporation of substantially hexagonal silicon carbide are useful for electromagnetic radiation frequency conversion at near infrared wavelengths. Such devices may be operated inter alia as second harmonic generators or as parametric downshifters.

Abstract: Incoherent light sources depending on phosphors which may simultaneously emit at more than one wavelength are provided with multiple dielectric coatings to suppress a portion of the emission and thereby enhance the remainder. The use of such coatings with frequency up-converting phosphors as well as downconverting phosphors is described.

Abstract: The hydrated and deuterated forms of lithium formate are found to be useful nonlinear materials for use over a wavelength range including the visible spectrum. While conversion efficiency is inferior to that of lithium niobate or barium sodium niobate, resistance to radiation damage is significantly greater. Operation at power levels in excess of 106 watts/cm2 has resulted in no perceptible damage. These materials are suitably incorporated in second harmonic generators as well as in other parametric devices.

Abstract: A projection visual display system utilizes at least one laser output line in the blue portion of the spectrum together with a phosphor coating which emits at least one additional color. Means for selectively reflecting laser light on the one hand and absorbing it within the phosphor so as to produce phosphor emission on the other hand are described.
