Zirconium fluoride (ZrF4)-based glass preforms made by the rotational casting process were treated prior to fibre drawing to eliminate pre-existing defects. Emphasis was given to the removal of external defects by different surface preparation method

Buffer layers of cubic silicon carbide were formed by reaction of (100) Si substrates with propane in hydrogen at 1380–1400°C. Reaction times ranged from 5 to 600 s. Reproducibility was improved by wet etching of substrates. Even for buffer-layer

Potassium bromide single crystals have been prepared with 10.6-..mu..m bulk absorption coefficients smaller than the intrinsic value for potassium chloride. Of several halogen-producing vapors studied, that of carbon tetrachloride is most effective i

In the absolute method for determining thermal conductivity K, the difference in temperature between two points along a rod is measured under conditions of steady‐state flow of heat. The thermal diffusivity κ may also be determined from measuremen

The thermal conductivities of Y2O3, Y2O3:Nd3+, Y3Al5O12:Nd3+, and LaF3 have been measured from 77°–300°K by a steady‐heat‐flow method. The densities of these crystals and of LaF3:Nd3+ have been determined in the same temperature range, using

The kinds and magnitudes of radiations present in the various locations near nuclear reactors are discussed as well as the mechanisms of interaction of radiation with matter, namely, group fragmentation, molecular scission, and polymerization. Techni

Laser emission at 172 nm has been produced by pumping a Nd:LaF3 crystal with incoherent Kr*2 radiation at 146 nm. The 5‐ns pulse contained approximately 20–30 μJ of energy. Fluorescence measurements indicate potential for tuning from 170–175 n

Absorption coefficients smaller than 0.001 cm-1 can, with more or less difficulty, be measured by several techniques. With diligence, all methods can be refined to permit measurement of absorption coefficients as small as 0.00001 cm-1. Spectral data
