Concentrically distributed silicon photonic grating arrays generate long-range Besse–Gaussian beams, enabling rotational and range measurements over obstacles. This compact and mass-producible chip ...

An all fiber-based approach to generating special optical beams, called Bessel beams, could open up new applications in imaging, optical trapping and communications. Bessel beams look quite different ...

As a vector version of scalar Bessel beams, Poincaré–Bessel beams (PBBs) have attracted a great deal of attention due to their non-diffracting and self-healing properties as well as the presence of ...

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 ...

To address porosity and defects in metal 3D printing, Lawrence Livermore National Laboratory researchers experimented with exotic optical laser beam shapes known as Bessel beams — reminiscent of ...

The big-picture plan starts with using laser propulsion in the coming decades on near-Earth space missions, journeys to the moon, and visits to near-Earth asteroids. Within 50 years, he hopes for ...
