The coils of fiber wrapped around the aluminum drums inside the chassis turned out to be the amplifier; fed by a semiconductor seed laser, the light pulse travels through the ytterbium-doped fiber ...

If the laser has exactly the right frequency ... “We use indium ions because of their favorable properties for achieving high levels of accuracy. Ytterbium ions are also added to the crystal for ...

Methane, like carbon dioxide, is a significant contributor to global warming. A high-power ytterbium thin-disk laser powers an optical parametric oscillator (OPO), which generates steady ...

The majority of fibre lasers are ytterbium-doped lasers operating at wavelengths of ∼1 μm, serving as replacements for or alternatives to both YAG-crystal and CO 2-gas lasers. Like conventional ...

ASP Isotopes uses QE, not AVLIS as its laser-based enrichment approach ... the commissioning phase for both the Silicon-28 and the Ytterbium-176 facilities. The company expects to commence ...

By tightly confining ytterbium in the ideal potential of a magic-wavelength optical lattice, the lattice clock pushes the frontiers of atomic timekeeping. We explore enhanced quantum control, ...

he performed groundbreaking experiments on a new optical atomic clock based on laser-cooled and -trapped ytterbium atoms. His research interests include atomic, molecular and optical (AMO) physics, ...

Recent research published in Physical Review Letters by PTB (Physikalisch-Technische Bundesanstalt) details the development of a new indium-ytterbium crystal optical clock, which achieves an accuracy ...

If the laser has the correct frequency ... For efficient cooling, ytterbium ions are added to the crystal." One of the challenges was the development of an ion trap that provides high-accuracy ...
