Application of Erbium Metal (Er)

Erbium’s main application is found in its pink Er3+ ion, known for its optical fluorescence capabilities, making it especially valuable in some laser technologies.

When erbium is doped into glass or crystals, it serves as a medium for optical amplification.

In this setup, the Er3+ ions are excited optically around 980 or 1480 nm wavelengths, subsequently emitting light at 1530 nm via stimulated emission.

This mechanism facilitates a remarkably straightforward laser amplifier design for signals conveyed through optical fibers.

The wavelength of 1550 nm is critically significant for optical communication systems, as it is the wavelength at which standard single-mode optical fibers exhibit the least amount of loss.
