crystal laser
A @S05736@ in which the @A00106@ is composed of ionic species supported in a crystalline host. The first @L03459@ used a ruby crystal in which chromium ions as the @A00106@ were supported in an aluminium oxide (sapphire) crystal. One of the most common crystal lasers involves neodymium atoms in a yttrium aluminium garnet host crystal (the @Y06721@:Nd @L03459@).
