Archaeologists have long wondered why the people of Anglo Saxon England began using more silver coins and fewer gold coins between 660 and 750 AD. Researchers in Europe now say they have developed a method to help find the answer. This technology combines laser ablation with traditional trace element analysis to match the isotopic abundance of silver bars in coins with known sources of metal ores ...
Researchers at the University of Sydney combined photon filters and modulators on a single chip, enabling them to accurately detect signals on the broadband RF spectrum. This work brings photonic chips closer to one day, potentially replacing larger and more complex electronic RF chips in fiber optic networks.The Sydney team utilized stimulated Brillouin scattering technology, which involves conve...
TAU Systems, a manufacturer of ultra fast compact laser plasma accelerators, announced today that it has successfully upgraded the existing desktop terawatt laser (UT 3) at the University of Texas to a new and improved performance that provides power for compact particle accelerators. The upgraded UT 3 driver laser can now generate ultra short pulses with a peak power of 40 terawatts.This upgrade ...
Researchers from Bayreuth University and Konstanz University are developing new methods to control ultra short laser emission using soliton physics and two pulse combs in a single laser. This method has the potential to greatly accelerate and simplify laser applications.Traditionally, the pulse interval of lasers is set by dividing each pulse into two pulses and delaying them at different, mechani...
The attosecond level ultra short laser pulse provides a powerful method for detecting and imaging ultra short processes, such as the motion of electrons in atoms and molecules.Although ultra short laser pulses can be generated, generating ultra short and high-energy pulses is a continuous challenge. In order to expand the photon energy, photon flux, and continuous bandwidth of isolated attosecond ...
