With the development of ultra intense laser technology, MeV ions from thelaser foil interaction have been obtained by different mechanisms, such astarget normal sheath acceleration, radiation pressure acceleration,collisionless shock acceleration, breakout afterburner, and a combination ofdifferent mechanisms. These energetic ion beams can be applied in fast ignitionfor inertial confinement fusion, medical therapy, and proton imaging. However,these ions are mainly accelerated in the laser propagation direction, and theion acceleration in an azimuthal orientation is scarcely mentioned. Here, adoughnut Laguerre Gaussian LG laser is used for the first time to study thelaser plasma interaction in the relativistic intensity regime in threedimensional particle in cell simulations. Studies have shown that a novelrotation of the plasma is produced from the hollow screw like drill of a LGmode laser. The angular momentum of the protons in the longitudinal directionproduced by the LG laser is remarkably enhanced compared with that produced bythe usual laser pulses, such as linearly and circularly polarized gaussianpulses. Moreover, the particles, including electrons and ions, can be trappedand uniformly compressed in the dark central minimum of the doughnut LG pulse.Such hollow structured LG laser may be used to investigate some difficultproblems, such as screw like drilling in the inertial confinement fusion, laserdriven particle accelerations, and pulsars in the astrophysical environment.
