摘要：

Highly HfO2 doped lithium niobate crystals have been grown. The experimental results indicate that LiNbO3:Hf (up to 4 mol%) can withstand the same light intensity, of 5 x 10(5) W cm(-2), as LiNbO3:Mg (6.5 mol%). And the OH- absorption bands of these LiNbO3:Hf crystals shift to 3487 cm(-1) from the 3484 cm(-1) for congruent pure LiNbO3. The difference spectra and fitting treatments show that the OH- absorption peak corresponding to (Hf-Nb(4+))(-)-OH- is located at 3500 cm(-1).
