摘要
We propose and demonstrate anti-diffracting vortex optical pin-like beams (VOPBs) generated by properly modulating both the amplitude and phase of an initial laser beam in Fourier space. Such VOPBs feature an autofocusing dynamics and outperform conventional higher-order Bessel beams and abruptly autofocusing beams.
