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 ...

Needle-shaped laser beams (NBs) featuring a long and narrow localization of photons can potentially allow non-diffracting pulses with undistorted temporal profiles. Using this kind of pulse in ...
