<unk>  with lid open showing frequency-doubled 532 nm green light<unk>  rod<unk> :YAG (neodymium-doped yttrium aluminum garnet;<unk> :Y3Al5O12) is a crystal that is used as a lasing medium for solid-state lasers. The dopant, triply ionized neodymium,<unk> (III), typically replaces a small fraction (1%) of the yttrium ions in the host crystal structure of the yttrium aluminum garnet <unk> , since the two ions are of similar size. It is the neodymium ion which provides the lasing activity in the crystal, in the same fashion as red chromium ion in ruby lasers. Laser operation of<unk> :YAG was first demonstrated by J.E. Geusic et al. at Bell Laboratories in 1964.
