Application
The most prominent use of erbium is to manufacture Erbium Dopant Fiber Amplifier (EDFA). Another application hot spot of erbium is laser, especially as a medical laser material. Used as laboratory reagent, optical glasses, structural ceramics, catalysts, electrical components and photo-optical material.
Another application hotspot of erbium is laser. Erbium laser is a solid-state pulsed laser with a wavelength of 2940nm, which can be strongly absorbed by water molecules in human tissues, so that a larger effect can be obtained with a smaller energy.
