Versatile Airy-Bessel Light Bullets

A study was conducted to explore a new approach to the development of Airy-Bessel light bullets. The proposed new approach was based on the unique properties of one-dimensional Airy wave packets. A new class of versatile three-dimensional linear light bullets were also reported that combined Bessel beams in the transverse plane with temporal Airy pulses. These Airy-Bessel waves were impervious to dispersion and diffraction effects, resulting in their evolution remaining free from depending critically on the material in which they propagated. It was demonstrated that an Airy pulse with a Gaussian spatial profile was generated by impressing a large cubic spectral phase on a femtosecond pulse from a mode-locked laser. The spatial profile was simply converted from a Gaussian to a Bessel beam by an axicon lens
