Ultrahigh intensity lasers inducing Micro-bubble implosions (MBI) have the potential to produce ultrahigh densities and consequently ultrahigh electrostatic fields. The field can be sufficiently strong so that gamma-rays passing near the imploded MBI core can be bent by the modification of the vacuum making transient gamma-ray lenses possible. At sufficiently high laser intensities the electrostatic fields could approach the Schwinger field. The substantial reduction of the pair creation threshold field from the vacuum in the finite volume of multiple focusing lasers has been shown previously. Here, we apply the same formalism to the Coulomb fields in the finite volume of the MBI to determine the probability of electron-pair creation verses initial density and cavity size.
