Applying the thulium laser allowed us to remove the calcified shell and then fragment the metallic tip into 3 smaller pieces and retrieve each piece individually and safely.
The rare earth elements or metals ("rare earths") include yttrium, lanthanum and 13 elements in the lanthanide group (cerium, praseodymium, neodymium, samarium, europium, gadolinium, terbium, dysprosium, holmium, erbium, thulium, ytterbium and lutetium).
