Holmium

Holmium-Oxide-DANTEK

Holmium,  is a chemical element with the symbol Ho and atomic number 67. Part of the lanthanide series, holmium is a rare earth element. It has the highest magnetic moment (10.6µB) of any naturally occurring element. Because of this it has been used to create the highest known magnetic fields by placing it within high strength magnets as a pole piece or magnetic flux concentrator.This magnetic property also has value in yttrium-iron-garnet (YIG) lasers for microwave equipment.Holmium lasers at a human eye safe 2.08 microns allowing its use in a variety of medical and dental applications in both yttrium-aluminum-garnet (YAG) and yttrium-lanthanum-fluoride (YLF) solid state lasers. The wavelength allows for use in silica fibers designed for shorter wavelengths while still providing the cutting strength of longer wave length equipment.
