As the initial stage of laser ignition, the effect of laser-induced plasma on nearby gaseous flow can have a considerable effect on further flame propagation. Laser-induced plasma is generated by concentrating a laser beam into a single point using a focusing lens. This paper presents a quantitative description of the perturbation of laser-induced plasma into a gaseous flow. Single-point laser-induced plasma generates fluctuations in the surrounding gaseous flow in a very short time (less than 200 ms), and the time-resolved velocity field can be obtained by the particle image velocimetry technique. Based on the angle and velocity of the velocity fields, it is possible to explain the movement of gaseous air flow quantitatively.
