| Abstract: | A technologically feasible process has been proposed for the preparation of a LiNbO3:Mg,B growth charge from a Li2CO3 + Nb2O5 + MgO + H3BO3 mixture. Using such a growth charge, we have grown LiNbO3:Mg,B crystals with a highly uniform dopant distribution. High-speed evaluation of optical homogeneity has shown that the LiNbO3:Mg,B crystals have high optical quality. Using amplitude–frequency response and d333 piezoelectric modulus measurements, we have demonstrated a high degree of unipolarity of the LiNbO3:Mg,B crystals. The optical damage resistance and homogeneity of the LiNbO3:Mg,B crystals have been assessed using photoinduced light scattering and laser conoscopy. The results suggest that LiNbO3:Mg,B crystals with a weak photorefractive effect can be regarded as a new optical material for laser light conversion. [ABSTRACT FROM AUTHOR] |
