| titleOfInvention | Optical material and method for manufacturing the same |
| abstract | (57) Abstract: The present invention provides an optical material having both high light sensitivity and excellent storage life of recording, and a method for manufacturing the same. SOLUTION: The optical material of the present invention is a single crystal having an electro-optical effect which is intentionally oxidized during or after crystal growth. As the single crystal, strontium barium niobate having a tungsten bronze type crystal structure is preferable, and the single crystal desirably contains a transition metal as an impurity. The method for producing an optical material according to the present invention is a method for producing an optical material comprising a single crystal having an electro-optical effect, wherein the single crystal subjected to the oxidation treatment is intentionally oxidized during or after the growth of the single crystal. Is characterized in that the absorption coefficient at a wavelength of 500 nm is controlled. |
