In a recent study published in Nature Communications, engineers at Duke University successfully manipulated laser beams to create intricate three-dimensional patterns known as optical knots. By ...

Tying light from lasers into stable 'optical knots' Interference patterns between overlapping laser beams could transmit encoded information over thousands of feet through chaotic environments ...

By overlapping several laser beams with specific properties and directing them through a series of lenses, interference patterns can form a stationary "optical knot" that looks something like a ...

A computational representation of an optical knot. The green areas are where the laser light is passing through. The dark areas inside are where the light interferes with itself, creating a twisting, ...

Currently, optical communication systems are employed for the internet, telecommunications, and other data-intensive services. These systems utilize light to transmit information over long distances.

1 To date, there are no standardized treatment guidelines for CRDD. We present a case of facial CRDD successfully treated with a pulsed dye laser and summarize the characteristics of the therapy of ...

In the present study, we use polymethylmethacrylate (PMMA) as a host matrix for laser dye doping due to their good transparency, resistivity, mechanical strength and optical homogeneity which play an ...

Abstract: Optical frequency chirp of an external-cavity laser is linearized by optimizing the modulation waveform for long-range FMCW optical ranging system. The modulation signal of the laser is ...
