Manganese Doped YAlO3 as a Multi-Use Material for Holographic Recording, Holographic-Sensing, Optical Storage and Lasers
Abstract
High quality single crystals of manganese doped yttrium orthoaluminate, Mn:YAlO3 and it's analogs have be been grown by the Czochraski technique. The crystals have been characterized by chemical analysis, x-ray diffractometry, optical spectroscopy, electron paramagnetic resonance spectroscopy, and tested in the holographic recording experiments. Mn(2-) Mn(3+), and Mn(4+) ions were identified and described in as-grown crystals. The reversible photoexcitation reaction Mn(4+) Mn(5+) + e and associated with it coloration and diffraction grating recording were studied in detail. The efficient diffraction grating recording was obtained in the crystals in one-color recording scheme and two-color recording scheme. Holographic recording tests of Mn:YAlO3 at IBM Almaden Research Center demonstrated high potential of the material of applications in optical data storage. The project generated significant interest among students and faculty at Norfolk State.
