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, ...

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 ...

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, ...

It is expected that Bessel-Gaussian beams will be widely used in laser radar, and laser sensing. The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied ...

Optical fiber, as the basic carrier of modern high-speed and high-capacity communication, is the key to the interconnection of the world. With the rapid development of the communications industry in ...

Researchers have shown that 3D laser printing can be used to fabricate a high-quality, complex polymer optical device directly on the end of an optical fiber. As described, this type of micro-optical ...

(Nanowerk Spotlight) Skyrmions, known for their intricate spin textures, are topological quasiparticles initially studied in particle and solid-state physics. They hold great promise as ...

A new method for imaging blood circulation and the flow within blood vessels could lead to faster and more precise assessments of capillary dynamics. In particular it should help the understanding of ...
