Generation of three-dimensional versatile vortex linear light bullets(Invited Paper)

We generate and measure the versatile vortex linear light bullet,which combines a high-order Bessel beam and an Airy pulse.This three-dimensional optical wave packet propagates without distortion in any medium,while carrying an orbital angular momentum.Its non-varying feature in linear propagation is verified by a threedimensional measurement.Such a novel versatile linear light bullet can be useful in various applications such as micromachining.
