Abstract
AbstractUV stable, high birefringence and low viscosity nematic liquid crystal mixtures were developed and their properties evaluated. Our new mixtures exhibit similar birefringence but ∼3.5X lower visco‐elastic coefficient than Merck E44. In the mean time, our new mixtures show better UV stability than those cyano‐biphenyls based commercial mixtures. To make a performance of new material more visible a high birefringence and relatively low viscosity liquid crystal mixture was developed for this experiment in conjunction with the voltage overdrive and undershoot technique. We demonstrated a liquid crystal light switch with response time ∼50 μs at room temperature and λ= 633 nm Potential application for sub‐millisecond laser beam steering is emphasized.
