| - Erbium is an element, number 68 on the periodic table. (TNG: "Manhunt" )
- Erbium (symbol Er) is a chemical element, atomic number 68 on the periodic table.
- Erbium's principal uses involve its pink-colored ions, which have optical fluorescent properties particularly useful in certain laser applications. Erbium-doped glasses or crystals can be used as optical amplification media, where erbium ions are optically pumped at around 980 nm or 1480 nm and then radiate light at 1530 nm in stimulated emission. This process results in an unusually mechanically simple laser optical amplifier for fiberoptically transmitted signals. The 1550 nm wavelength is especially important for optical communications because standard single mode optical fibers have minimal loss at this particular wavelength. In addition to optical fibre lasers, a large variety of medical applications (i.e. dermatology, dentistry) utilize erbium ion's 2940 nm emission (see Er:YAG laser

In addition to optical fibre lasers, a large variety of medical applications (i.e. dermatology, dentistry) utilize erbium ion's 2940 nm emission (see Er:YAG laser), which is highly absorbed in water (absorption coefficient about 12,000/cm).
