The Ariane 6 will be the first large rocket to utilise a laser ignition system which has been developed by Austrias Carinthian research center (CTR) and previously deployed in automotive and turbine engines. A solid state laser offers an advantage over electrical ignition systems in that it is more flexible with regards to the location of the plasma within the combustion chamber, offers a much higher pulse power and can tolerate a wider range of fuel-air mixture ratios.
