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 ...

Bessel beams of light are also interesting from a practical point of view — as optical tweezers, for example. Such beams can also carry orbital angular momentum that can be used to encode information.

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, ...

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 ...
