    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: 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: 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.
