Airy-Bessel位形波包被认为是在自由空间中传播时没有时空扩展的奇异局域线性光子弹（LLB）。对理想Airy-Bessel波包在自由空间中的传播进行了研究，得到了一些新的结果。三次空间诱导色散（SID）稍微加宽艾里脉冲，而二次SID不能在时间上改变ABW传输模式。因此，ABW，虽然保持为上级局部线性波包，但不能被视为绝对LLB。此外，立方SID也降低了艾里脉冲峰值在传播过程中的纵向加速度。
Airy-Bessel configuration wave packets are believed to be exotic localized linear light bullets (LLBs) without spatiotemporal spread during propagation in free space. By carefully studying the propagation of ideal Airy-Bessel wave packets (ABWs) in free space, several new results were obtained. Cubic spatially induced dispersion (SID) slightly broadens Airy pulses while quadratic SID cannot temporally change ABWs transmission modes. Hence, ABWs, although remaining as superior localized linear wave packets, cannot be regarded as absolute LLBs. Moreover, cubic SID also decreases the longitudinal acceleration of the Airy pulse peak during propagation.
