Abstract : In 1966 researchers first noted stimulated emissions from organic dye materials. Since that time, a wide array of organic dyes have been investigated and developed for use in what are now known as dye lasers, wherein an organic compound in solution replaces a gas or crystal (e.g., ruby) or the like as the active optical element. Laser dyes are so-called because they typically possess auxochromic groups such as oxygen and nitrogen and conjugated double bonds characteristics of classic organic dyes.
