  4. Abstract:
  5. In this paper, two-axis dielectric laser acceleration is proposed by introducing a dual-grating base laser accelerator structure excited with two orthogonal propagating ultrashort laser pulses. A 2D periodic structure is designed that provides phase synchronicity between the relativistic particle beam and orthogonal propagating laser pulses. In this way, the particle beam can gain energy from both laser pulses simultaneously. It is numerically demonstrated that utilizing this method increases both the acceleration gradient and acceleration factor up to90%in comparison with dual-grating dielectric laser acceleration. Also, deflecting force elimination, particle beam quality, and bunch acceleration efficiency can be improved using this method. © 2020 Optical Society of America
