Abstract: A spatiotemporal optical vortex (STOV) with transverse orbital angular momentum can induce some novel properties in high-energy-density physics. However, the current STOV pulse energy is limited to the mJ level, which greatly hinders the development of the research field of relativistic laser–matter interaction. Combined with the large-scale grating pair in high-peak-power laser facilities, a method for generating STOVs with ultra-high intensity of up to 10 21 W/cm 2 is proposed. The numerical simulation proves that a wave packet with 60 fs duration and 83 J energy can be generated in the far-field, maintaining an integral spatiotemporal vortex construction. Simultaneously, STOVs with 1.1 mJ single-pulse energy were obtained in a proof-of-principle experiment, and characterized by a home-made measuring device.
