N2 - We present a three temperature plasma model of dual-pulse laser ignition of the hydrogen-air mixture. The results suggested that the calculated ignition delay time strictly depends on the model dimension, showing the highest values for the zero-dimensional model. Kinetic scheme, which includes the avalanche and multiphoton ionization showed a good agreement with the measured ignition delay time. Analysis of energy exchange and ignition mechanisms confirmed mostly thermal effect of the near infrared laser pulse, showing dependence not only on the maximum laser intensity but also on the laser intensity profile.
