The explosion in attosecond technology has opened the gate to investigatingmany unexplored areas which require ultrahigh spatial and temporal resolution.In the area of nuclear physics, using gamma-rays with ultrahigh resolution intime and space will help to investigate intra-nuclear dynamics in anunprecedentedly explicit way. However, the generation of ultrahigh brillianceattosecond gamma-ray pulses with current-generation laser facilities has notbeen reported. In this letter, we propose a novel method to generate highcharge (~1nC) attosecond (<200 attosecond) electron bunch by the near-thresholdself-injection in a wakefield accelerator. We demonstrate the ability togenerate an ultrahigh-brilliance (> 2*1024 photons s-1mm-2mrad-2 per 0.1%BW)attosecond (<200 attosecond) gamma-ray (Emax > 3 MeV) pulse via nonlinearCompton scattering. To the best of our knowledge, this is the first methodreported to generate attosecond gamma-ray photon source usingcurrent-generation laser. This is the shortest gamma-ray photon and the highestbrilliance photon source in MeV range (orders higher than the resultsreported). This method can be widely applied for experimental generation of 100keV to several MeV high brilliance attosecond gamma-ray sources with current~100 TW laser facilities, which will benefit basic science such as applicationin ultra-high resolution radiography.
