To develop a new ignition method, authors carrieg out a series of experiments about the ignition process of H2-O2O3/ H2-O2-O3-Ar mixtures with an excimer laser. From laser-focusing ignition experiments, we found that the Minimum Incident Laser Energy for ignition (MILE) decreased drastically with the concentration of ozone, and the plane ignition was possible with a laser sheet, providing the possibility of the bulk ignition with UV light. The schlieren observation of the process of plane ignition with a high-speed framing camera showed that the float part of mixture irradiated with the laser sheet ignited simultaneously. And then, the flame kernel grew extremely rapidly.
