Magneto-optical element material formed of magnetic garnet single crystals |
| 摘要 |
A material made of magnetic garnet single crystals has excellent characteristics particularly in a wavelength band of from 950 to 1070 nm, which is usable for a wavelength 980 nm for pumping light of erbium doped fiber amplifier, and for a wavelength of 1017 nm for pumping light of an praseodymium doped fiber amplifier. One example of the material is made of magnetic garnet single crystals expressed by a composition formula of Nd3-xBixFe5O12 (0.5</=x</=1.9), the single crystals being formed by liquid-phase epitaxial growth on a non-magnetic garnet substrate having a lattice constant <a> specified in the range of 12.61 ANGSTROM </=a</=12.63 ANGSTROM . The material is suitably used for a magneto-optical element having a wavelength band from 950 to 1070 nm. The non-magnetic garnet substrate can be made of a material having a composition formula expressed by Gd3-yNdySc2Ga3O12 (1.0</=y</=1.4).
