Erbium's atomic number is 68 and its symbol is Er. Erbium is a rare earth element that is mainly used in laser technology. Pink-colored erbium compounds are used to create laser amplifying glass or crystal lenses. These laser amplifying lenses are used in fiber optics as well as dental surgery. The laser is easily absorbed by watery tissue which helps dental surgeons to make very hot but shallow cuts.
