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 ...

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 ...

Bessel beam microscopy, and the techniques that preceded it, are generally used to image live cells in 3D. Bessel beams have a greater capability than other super-resolution imaging techniques for ...

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, ...

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 ...

A fibre-based source of near-ideal Bessel beams will be crucial for applications that require remote beam delivery as well as diffraction-free propagation. Scientists at OFS Laboratories in Somerset, ...

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 ...

Researchers have developed a new type of organic vortex laser, which is a laser that emits a helical beam of light. In the future, miniature arrays of these vortex lasers, each with a slightly ...
