More info

Barium Titanate (BaTiO3) Single Crystal Substrate is known for its outstanding photorefractive properties, featuring high self-pumped phase conjugate reflectivity and efficient two-wave mixing (optical amplification). These characteristics make it highly promising for optical information storage and advanced photonic applications. BaTiO3 is also an essential substrate material for ferroelectric and electro-optic devices, supporting innovations in modulators, sensors, and memory technologies. Various types, including pure BaTiO3, cerium-doped (Ce:BaTiO3), and rhodium-doped (Rh:BaTiO3), are available to meet different research and industrial needs. Heeger Materials provides high-quality BaTiO3 Crystal Substrate for cutting-edge optical and electronic advancements.
