We propose a scheme to generate gamma-ray photons with an orbital angularmomentum (OAM) and high energy simultaneously from laser-plasma interactions byirradiating a circularly polarized Laguerre-Gaussian laser on a thin plasmatarget. The spin angular momentum and OAM are first transferred to electronsfrom the driving laser photons, and then the OAM is transferred to thegamma-ray photons from the electrons through quantum radiation. This scheme hasbeen demonstrated using three-dimensional quantum electrodynamicsparticle-in-cell simulation. The topological charge, chirality andcarrier-envelope phase of the short ultra-intense vortex laser can be revealedaccording to the pattern feature of the energy density of radiated photons.
