Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that require light to remain concentrated over long ...

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 ...

Laser powder bed fusion (LBPF), a 3D printing technique commonly used to make metal parts, creates large thermal gradients between areas hit by the laser and areas not being struck. This creates pools ...

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 ...

PowerPhotonic, a developer of freeform, wafer-scale optics, this week launched a new Variable Beam Shaper, while exhibiting at SPIE Sensors and Imaging exhibition and conference, in Edinburgh, UK. The ...
