Abstract
In this paper, taking the effects of avalanche ionization and electron-ion recombination into account, a model for plasma ignition is presented. Assuming the laser pulse has a rectangular temporal shape, an analytical solution of the plasma ignition can be given. Using this model, the dependence of the time needed for plasma ignition on the laser parameters, such as laser power density and laser wavelength as well as the material reflective index can be given.
