- For many targets of interest, the thickness is small compared to the conduction length during the engagement. In addition, the laser-material interaction region can be treated as flat. We have studied this regime with our 25 kW solid-state laser. We have demonstrated that airflow can reduce by approximately 40% the energy required to break through a thin target. This reduction is caused by the bulging of the softened material and the tearing and removal of the material by aerodynamic forces. We present elastic modeling which explains these results.
