Liquid Crystal Elastomer (IMAGE) Kent State University Caption A liquid crystal elastomer is used as a mechanically tunable mirrorless "rubber" laser in the lab of Peter Palffy-Muhoray, Ph.D., associate director of the Glenn H. Brown Liquid Crystal Institute and professor of chemical physics at Kent State University. The elastomer has properties that enable it to precisely emit laser light, without the use of mirrors, while being stretched.
