Abstract: It is shown that the air breakdown region and the erosion torch during an inclined fall of the laser radiation on the target are separated in time and space—namely, the electron density is higher in the region of the air breakdown, while the concentration of aluminum atoms is higher in the erosion torch. The mechanism of the motion of the laser plasma is determined and the formation time of the erosion torch is evaluated allowing for the film boiling mechanism.
