  • Employing thermal and Kα imaging to analyze electron beam emission.
  • Varying laser parameters such as intensity ratio, delay, total energy, and prepulse.

    • Main Results:

    • Achieved guiding of relativistic electron beams with reduced divergence (2.7x) and increased current density (1.8x).
    • Optimized parameters (4-6 ps delay, 10:1 intensity ratio, 186 J total energy) yielded reduced emission size and increased peak/total emission.
    • Experimental findings were reproduced through modeling, attributing enhancements to self-generated magnetic fields.

    Conclusions:

    • The dual-laser pulse scheme effectively guides relativistic electron beams in solid targets.
    • This technique offers significant improvements in fast-electron beam properties.
    • The demonstrated guiding mechanism shows promise for advancing fast-ignition inertial fusion energy applications.
