| Zusammenfassung: | A series of In:Mn:Fe:LiNbO3
crystals were prepared with fixed concentrations of
Fe2O3,
MnCO3 and various
concentrations of In2O3.
Their ultraviolet-visible (UV-Vis) absorption spectra were measured in order
to investigate their defect structure. The optical damage resistance of
In:Mn:Fe:LiNbO3
crystals was characterized by the transmitted beam pattern distortion
method. It increases remarkably when the concentration of
In2O3 is over its threshold
concentration. The optical damage resistance of
In(3.0 mol%):Mn:Fe:LiNbO3
crystal is two orders of magnitude higher that of the
Mn:Fe:LiNbO3 crystal. The
dependence of the defects on the optical damage resistance of the
In:Mn:Fe:LiNbO3 crystals
was discussed. |
