A Gaussian beam is transformed into a Bessel beam using a binary axicon and then reshaped by a flat multilevel diffractive lens into a micron-sized optical bottle beam, enabling long-distance ...
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 ...
