Bessel Beams are impossible to create, can’t be destroyed, and don’t diffract. In other words, physics has discovered yet another thing that makes no sense. Bessel beams bear the name of Friedrich ...

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications. Bessel beams look quite different ...

Terahertz (THz) radiation from laser plasmas features with ultrabroad bandwidth, which is attractive for many applications. Significant efforts have been made to enhance its conversion efficiency, ...

SEM is a common microscopy technique for scanning a surface. In SEM, a beam of high-energy electrons is fired from an electron gun towards a sample of interest. The beam of electrons is controlled by ...

PowerPhotonic, a developer and manufacturer of freeform, wafer-scale optics, based in Fife, UK, has this week been exhibiting and presenting an invited paper at SPIE Sensors and Imaging, in Amsterdam, ...

The alternative text for this image may have been generated using AI. The approach is the first application of plane-illumination microscopy to single cells. Plane illumination confines excitation to ...

Light is pushy. The physical pressure of photons is what allows for solar sail space missions that ride on sunlight, and what allows for dreams of lasers that will push those sails even faster. And ...

It seems like we’re getting closer to the Star Trek future by leaps and bounds these days. We recently learned that a NASA scientist has set his sights on building a warp drive, and now news has come ...
