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 ...

Newport (Irvine, CA) has introduced a new refractive beam shaper that converts Gaussian laser beam input to produce a collimated, flat-top beam that can propagate without change in power and intensity ...

Compatible with lasers that emit at UV, visible, and near-IR wavelengths, the Flat-Top 2 Generator is a laser-beam-shaping module that converts a Gaussian beam into a focused flat-top profile, with ...

Gaussian-shaped laser-beam frequency spectrum can now be translated into a collimated flat-top beam that propagates with little change in power and intensity or loss of uniformity over large distances ...

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 ...
