The zone-center E_2g modes play a crucial role in MgB_2, controlling the scattering mechanisms in the normal state as well the superconducting pairing. Here, we demonstrate via first-principles quantum-field theory calculations that, due to the anisotropic electron-phonon interaction, a hot-phonon regime where the E_2g phonons can achieve significantly larger effective populations than other modes, is triggered in MgB_2 by the interaction with an ultrashort laser pulse. Spectral signatures of this scenario in ultrafast pump-probe Ram
