Abstract

Ultrafast fiber laser light sources attract enormous interest due to the booming applications they are enabling, including long-distance communication, optical metrology, detecting technology of infra-biophotons, and novel material processing. In this paper, we demonstrate 175 fs dispersion-managed soliton (DMS) mode-locked ytterbium-doped fiber (YDF) laser based on single-walled carbon nanotubes (SWCNTs) saturable absorber (SA). The output DMSs have been achieved with repetition rate of 21.2 MHz, center wavelength of 1025.5 nm, and a spectral width of 32.7 nm. The operation directly pulse duration of 300 fs for generated pulse is the reported shortest pulse width for broadband SA based YDF lasers. By using an external grating-based compressor, the pulse duration could be compressed down to 175 fs. To the best of our knowledge, it is the shortest pulse duration obtained directly from YDF laser based on broadband SAs. In this paper, SWCNTs-SA has been utilized as the key optical component (mode locker) and the grating pair providing negative dispersion acts as the dispersion controller.

Ytterbium

See more Ytterbium products. Ytterbium (atomic symbol: Yb, atomic number: 70) is a Block F, Group 3, Period 6 element with an atomic weight of 173.054. Ytterbium Bohr ModelThe number of electrons in each of Ytterbium's shells is [2, 8, 18, 32, 8, 2] and its electron configuration is [Xe]4f14 6s2. The Ytterbium atom has a radius of 176 pm and a Van der Waals radius of 242 pm. Ytterbium was discovered by Jean Charles Galissard de Marignac in 1878 and first isolated by Georges Urbain in 1907.Elemental Ytterbium In its elemental form, ytterbium has a silvery-white color. Ytterbium is found in monazite sand as well as the ores euxenite and xenotime. Ytterbium is named after Ytterby, a village in Sweden. Ytterbium can be used as a source for gamma rays, for the doping of stainless steel, or other active metals. Its electrical resistivity rises under stress, making it very useful for stress gauges that measure the deformation of the ground in the even of an earthquake.
