A Gaussian beam is transformed into a Bessel beam using a binary axicon and then reshaped by a flat multilevel diffractive ...
Optical fibre, as the basic carrier of modern high-speed and high-capacity communication, is the key to the interconnection of the world. With the rapid development of the communications industry in ...
Most laser sources produce Gaussian beams that diverge as they propagate. This natural spreading limits their effectiveness in applications that ...
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 ...
