Ultra-short laser pulses mark a new kilogram prototype

International efforts that have been going on for years to redefine the unit of measure and find a constant gauge.
At the National Metrology Institute of Germany (Physikalisch-Technischen Bundesanstalt (PTB)) a solution is being sought for this in natural constants – in atoms that comprise a certain crystal.
Pure silicon is key to the definition of a new, constant kilogram.

To align the spheres for the numerous measurements, markings are necessary that inflict the least damage possible.

In its search for a suitable method the PTB in Braunschweig found what it was looking for at Micreon.
