Description
Optical quality Cr3+-dopeed Sr0.6Ba0.4Nb2O6 (SBN:60) single crystals have been grown by the Czochralski technique with boules as large as 2 cm in diameter and 5 cm long being grown. The doping of 0.01 wt% Cr3+ on the 6-fold coordinated Nb5+ site increases the dielectic constant approximately 15% and reduces the phase transition temperature from 750 to 720C. Photorefractive fanning measurements show a response time of 0.9s at 40 mW/cm2, a value nearly three times faster than found in Ce3+-doped SBN:60 crystals
