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 ...

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 ...

Last year, we looked at three potential “tractor beam” technologies being evaluated by NASA to deliver planetary or atmospheric particles to a robotic rover or orbiting spacecraft. At the time, the ...

Optical fibre, 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 ...

In the good old days of analog scopes, you pretty much had only one choice for frequency response—Gaussian. That came about because of the natural way in which the behavior of multiple components with ...

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, ...

LASER COMPONENTS offers Bessel lens assemblies which are used to form non-diffractive Bessel laser beams, consisting of two concentric rings of equal power. Bessel lens assemblies consist of an axicon ...
