In KNSBN several crystallographic sites can be partially empty which allow crystal composition to be tailored. The magnitude of longitudinal r51 and transverse r33 electrooptic coefficient depend greatly on the ratios of BaNa and KNa. So either r33 or r51 can be made large, absorption and response wave range can be controlled in the desired spectral range by changing the dopant and its concentration.
