Abstract

Laser floating zone processing methods are particularly suitable for studying crystal growth and the development of texture from the melt in many materials used n electrooptics, for example. A system is descrbed that allows different laser wavelengths to be used, and first results on BSCCO superconducting fibers processed using different lasers are presented. The Figure compares textures produced using Nd:YAG and CO2 lasers
