Er:LiNbO3crystals were grown by Czochralski method.The tape of the crystals were Er(1mol): LiNbO3
Er(2mol):LiNbO3
Er(3mol):LiNbO3
Li/Nb=0.94.Through the measurements of the absorption spectra
we confirm that the absorption edge continuous moves to long wavelength.We measure the emission spectra of the Er:LiNbO3crystals
explain that the emission ability of the Er3+ increases with the increase in Er3+ codoped concentration by Er3+ ions cluster defect centra.The result of the photodamage...
