    • Abstract
  • Through discussing physical mechanism of optical breakdown in air caused by high power laser and ionization,the formula of free electron density in laser focus regime was attained.In addition,the breakdown threshold formula was also obtained after considering the energy loss of electron elastic collision and recombination.The calculated results are consistent with the experimental data.
