In order to achieve higher fuel efficiencies, and lower fuel emissions while maintaining engine specific power densities, many practical combustion systems have resorted to advanced combustion regimes wherein ignition is severely impeded. Laser ignition has proved instrumental in unlocking the true potential of such combustion modes. This is the third conference that attempts to collate the latest developments in laser and laser technologies for the feasibility of laser ignition in practical combustion systems. In parallel, the latest developments in non-laser ignition systems will also be presented. Also, studies that enhance our understanding of the ignition process will also be presented. Included in this conference are guest lectures from leading authorities on laser ignition technologies.
