Stimulated Emission of Infrared Radiation from Ytterbium Activated Silicate Glass
The stimulated emission of Yb/sup 3+/ in a lithium-magnesium-- alumino-- silicate glass that was made to oscillate at a wavelength of 1.0l5 mu at liquid N temperature and lower is described. AExpand

Defect centers in a pure‐silica‐core borosilicate‐clad optical fiber: ESR studies
An electron‐spin‐resonance (ESR) study has been carried out on γ‐ray‐induced color centers in a pure‐SiO2‐core B2O3⋅3SiO2‐clad prototype optical fiber and in bulk glasses of the core and claddingExpand

Optical waveguides formed by thermal migration of ions in glass
Optical waveguides were formed by increasing the index of refraction of a glass substrate by exchanging constituent glass ions in a small region near the surface. The glass refractive index isExpand

The Sensitized Luminescence of Manganese‐Activated Calcite
Synthetic manganese‐activated calcites are shown to be practically inert to ultraviolet excitation in the range 2000–3500A, while they are luminescent under cathode‐ray excitation. The incorporationExpand

Diode‐pumped single‐mode fluorozirconate fiber laser from the 4I11/2→4I13/2 transition in erbium
Diode‐pumped cw lasing at 2.71, 2.75, and 2.78 μm from an erbium‐doped ZBLAN single‐mode fiber is reported for the first time. A threshold of 4 mW absorbed power at 792 nm was obtained for the 2.71Expand

Rayleigh scattering in ZrF4-based glasses
Light scattering in a 51.53 ZrF4 - 20.47 BaF2 - 5.27 LaF3 - 3.24 AlF3 - 19.49 LiF glass was investigated for the first time both as a function of wavelength and of angular distribution. The measuredExpand
