Abstract :
Summary form only given. Nematic liquid crystals (LCs) have remarkable peculiarity in laser beams: the same material may totally change its response to laser radiation owing to special preparation and/or the geometry of irradiation. They may be used for optical power limiting and, on the other hand, for high-damage-threshold optics and beam-quality sensors for high-power lasers.
