Bethel University has been a leader in Christian higher education since 1871. Come see why we're one of the most ...

are routinely created by interfering optical laser beams. These so-called optical lattices act as versatile potential landscapes to trap ultracold quantum gases of bosons and fermions. They form ...

By using paired, offset optical combs and RF electronics, researchers devised a unique atomic-clock architecture.

The objective of this work was the optical trapping of λ-DNA on a metallic nanostructure ... the reversible trapping and release of the DNA was achieved by switching the fs laser irradiation on and ...

Through tuning physical parameters of optical-controlled devices, such as effective index, bandwidth and dispersion, the output characteristics of free-running lasers can be manipulated for widespread ...

Bray McCollum said. The U.S. military is using laser weapons to shoot down drones. During a recent large-scale exercise in the Indo-Pacific, the U.S. military used directed energy, or laser ...

Laser-cooled atomic gases ... When these atomic gases interact with light inside an optical cavity (i.e., a structure designed to trap and enhance light), they can give rise to effects that ...

This unique tour reveals five of the city's most surprising optical illusions, from the perfectly framed dome seen through the Knights of Malta keyhole to the vanishing columns of St Peter's Square.

Abstract: In this paper, the photo-stimulated discharge (PSD) current spectra of polyimide (PI) are obtained by the optical parametric oscillator (OPO) laser to characterize the deep space charge ...
