YAG:Nd,: ,-PD and Czochralski Growth and Propertiesshape of the fibers permits the development of new optical components based on YAG crystals that have optical and thermal efficiencies that approach those of silica glass fibers. This chapter compares the physicochemical properties of YAG bulk and fiber crystals. The potential development of lasers based on single-crystalline fibers is discussed.

Spätmoderne I – Jürgen Habermasffects growth patterns in the manufacturing industry. Hence, this research constitutes a departure from the traditional approach of applied growth studies based on aggregate cross-country data. It supplies novel empirical findings on some central issues in the new endogenous growth literature.
