Understanding the dynamics of laser‐produced plasma is essential for increasing the available thrust and energy conversion efficiency from a pulsed laser to a blast wave in a gas‐driven laser‐propulsion system. The performance of a gas‐driven laser‐propulsion system depends heavily on the laser‐driven blast wave dynamics as well as on the ionizing and/or recombining plasma state that sustains the blast wave. In this study, we therefore develop a numerical simulation code for a laser‐driven blast wave coupled with time‐dependent rate equations to explore the formation of unsteady ionizing plasma produced by laser irradiation. We will also examine the various properties of blast waves and unsteady ionizing plasma for different laser input energies.
