Barium Borate Electro-Optic Crystal (BBO EOM)
The electro-optic effect changes a crystal's refractive index under an electric field parallel to its optical axis. The change is linear with applied voltage and depends on incident direction/polarization. Pockels-cell materials include BBO, KDP, DKDP, LiNbO3, LiTaO3, KTP, RTP and ADP. Ketong Optoelectronics' BBO electro-optic crystals offer temperature stability and laser-power handling advantages.
