Rare earth explained

Rare-earth magnet - Wikipedia

Rare-earth magnets are strong permanent magnets made from alloys of rare-earth elements. Developed in the 1970s and 1980s, rare-earth magnets are the strongest type of permanent magnets made, producing significantly stronger magnetic fields than other types such as ferrite or alnico magnets.

RP Photonics Encyclopedia - rare-earth-doped gain media ...

All rare-earth-doped gain media have in common that the pump and laser transitions are so-called weakly allowed transitions with fairly small oscillator strength. A consequence of this is that the upper-state lifetimes can be long, i.e. of the order of microseconds to milliseconds, so that substantial amounts of energy can be stored in such media. This property makes rare-earth-doped lasers ...
