In International Journal of Extreme Manufacturing, a new laser machining method that dynamically adapts its beam shape is proposed to fabricate microgrooves with ...

Researchers have developed a technique for improving accuracy of laser beam shaping and wavefront obtained by conventional methods with no additional cost by optimizing virtual phase grating.

Researchers have developed a new method for flexibly creating various needle-shaped laser beams. These long, narrow beams can be used to improve optical coherence tomography (OCT), a noninvasive and ...

Anamorphic beam shaping optics are used to transform elliptical laser beams to a round shape - for example before coupling them to single mode optical fibers. Conversely, there are cases where ...

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, ...

(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 ...

In a physics first, a team including scientists from UB and the National Institute of Standards and Technology (NIST) has created a way to make beams of neutrons travel in curves. These Airy beams ...

As we all know, light on its own tends to travel in a straight line. When it gets sent through an aperture like a flashlight, diffraction occurs, which causes the beam to widen and lose its intensity.

While beam-shaping strategies have allowed researchers to sculpt the cross-sectional shape of laser spots—using, for example, triangular beams to carve triangular channels—the interaction of such ...
