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 ...

Bessel beam microscopy, and the techniques that preceded it, are generally used to image live cells in 3D. Bessel beams have a greater capability than other super-resolution imaging techniques for ...

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 ...

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 ...
