摘要: An exact analytic expression for an ultrashort hollow-Airy wave packet is presented beyond the slowly varying envelope approximation. The combines hollow-Gaussian beam in spatial domain and Airy pulse temporal domain. spatiotemporal propagation dynamics of are analyzed by numerical simulations. During free space, intensity profile evolves from to Gaussian shape; retains shape over several Rayleigh ranges. acceleration property also demonstrated.
