The Bessel beam, with a significant depth of field and self-healing characteristics, has been applied in widespread applications, including quantum entanglement, underwater 3D imaging, optical ...

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 ...

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 at Heriot-Watt University have improved a fibre optic endoscope in a demonstrated of laser-enhanced chemical etching, and developed a way to significantly speed up such 3d patterning of ...

(Nanowerk News) While laser-based 3D printing techniques have revolutionized the production of metal parts by greatly expanding design complexity, the laser beams traditionally used in metal printing ...

Beam shaping device: Scanning electron microscopy image of the micro-optical element that’s 3D laser printed directly on the end of an optical fibre, showing the helical axicon (top) and the parabolic ...

Spreading the laser beam's intensity out reduces the temperature difference between sections of the part being printed. Laser powder bed fusion (LBPF), a 3D printing technique commonly used to make ...

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 ...
