Einfluß der Substruktur auf die optische Homogenität von Rubin-Laserstäben

The relation between mosaic structure and optical homogenity was measured of 90° ruby laser rod. The optical homogenity was measured by the interferometric method and the mosaic misorientation by Berg-Barrett method and the oscillation spectrometer respectively. The proportionality between the number of the interference stripes and the rotation of the mosaic blocks about an axis perpendicular to the growth axis and crystallographic c-axis was found.
