Abstract Ultrafast liquid crystal light valves are extensively utilized in high‐refresh‐rate displays and beam control shaping applications. Ferroelectric crystals, characterized by their ability to achieve microsecon response times when driven a 5 V voltage, particularly well‐suited for array‐type valves, such as display screens or adjustable gratings. This study employs optimized ferroelectric materials that exhibit high contrast (~1,000:1), ultra‐fast (<20 μs), polarity‐dependent...
