Paper Abstract

Doping a little Fe2O3 and Tb4O7 into LiNbO3, the double-doped crystal LiNbO3:Fe,Tb was grown by Czochralski method. Its diffractive efficiency and the four-wave mixing phase conjugate reflectivity were measured to be the similar to the single-doped LiNbO3: Fe crystal. But the response time of the double-doped crystal was measured to be tens seconds, showing a great improvement comparing with LiNbO3: Fe. The mechanism of the results was discussed by measuring and calculating the values of the photoconductivity.
