In recent years, ytterbium has emerged and developed rapidly in the two major fields of optical fiber communication and laser technology.

With the development of "information superhighway", computer network and long distance optical fiber transmission system require more and more high performance of optical fiber materials for optical communication. Because of its excellent spectral properties, ytterbium ions can be used as optical fiber amplification materials for optical communication, just like erbium and thulium. Although the rare earth element erbium is still the main role in the preparation of fiber amplifiers, the traditional erbium-doped quartz fiber has a small gain bandwidth (30nm), and it is difficult to meet the requirements of high-speed and large-capacity information transmission. Yb3+ ion has a much higher absorption cross section than Er3+ ion near 980nm, and the 1530nm light can be greatly enhanced through the sensitization of Yb3+ and the energy transfer of Erbium and YB3 +, thus greatly improving the amplification efficiency of light

Yb3+ fiber amplifier can realize power amplification and small signal amplification, so it can be used in fiber sensor, free space laser communication and ultra-short pulse amplification.

At present, China has built the world's largest single-channel capacity and fastest optical transmission system, and has the world's widest information highway. Fiber amplification and laser materials doped with ytterbium and other rare earths play a key role in this process.

The spectral properties of ytterbium are also used as high-quality laser materials, both as laser crystals, as laser glass, and as fiber lasers.
