Three-dimensional abruptly autofocusing by counter-propagating Airy pulses with radial Airy beam profile
Youngbin Park, Xiaolin Su, Qian Cao +1
We report the experimental observation of a three-dimensional abruptly autofocusing effect by synthesizing a radially distributed Airy beam with two counter-propagating Airy pulses…
