The aim of this paper is to investigate potential benefits of using a high-speed laser (10 kHz) to ignite and stabilize a liquid fuel flames by directly igniting droplets. Plasma is formed in droplets crossing the laser beam, not only at the focal point of the beam, leading to multiple ignition spots. The effects of laser frequency as well as laser energy is investigated for various injection parameters.
