Abstract
Optical absorption has been measured from 700 to 1300 nm for garnet si ngle crystals by substituting Dy or Ga for Gd or Al of Dy3Ga5O12 grown by the Czochralski method, and a suppression of unstable spiral-shape growth on Dy3Ga5O12 by the substitution was discussed relating the ab sorption spectra. The total absorption in the single crystals at the w avelength corresponding to the radiation from Ir crucible was decrease d relatively with the increase of Gd or Al content. The decrease of th is absorption in the single crystals is one of the causes to suppress the unstable spiral-shape growth.
