We demonstrate a versatile vortex linear light bullet as a vortex Airy-Bessel wave packet for the first time. Its non-varying three-dimensional (3D) vortex field in linear propagation is verified by 3D measurements.OCIS codes: (320.7090) Ultrafast lasers; (320.7100) Ultrafast measurements.Linear light bullets are 3D localized optical wave packets that propagate without broadening under the influence of dispersion and diffraction in linear media [1]. The non-varying property of the light bullet is useful for many applications such as optical tweezing, material modification, etc. Most of the linear light bullets such as X-waves and O-waves rely on a subtle balance between the dispersion and diffraction effects. Therefore, an X-wave (O-wave) works as a light bullet only for a specific material with proper dispersion and diffraction parameters. In contrast, an Airy-Bessel wave packet does not require the balance between the dispersion and diffraction effects since the Airy pulse and the Bessel beam are impervious to the dispersion and the diffraction respectively. Since the Airy-Bessel wave packet works as a linear light bullet for any linear medium, it is referred as a versatile linear light bullet [2].Advanced from the Airy-Bessel wave packet, we demonstrate a vortex Airy-Bessel wave packet as a versatile linear light bullet which contains a phase singularity for the first time. The vortex Airy-Bessel wave packet is formed by combining an Airy pulse and a higher order vortex Bessel beam. Its non-varying feature in linear propagation is revealed by measuring the evolution of the 3D intensity profile and the transverse phase profile. The versatile vortex light bullet will be useful for applications requiring non-varying high peak intensity with phase singularities. Fig.
