Abstract
A laser beam is utilized to ignite the fuel and oxidizer injected into a combustion chamber. An injector has a plurality of injector elements each injecting fuel and oxidizer into a flame holding zone adjacent the injector face plate where fuel and oxidizer are mixing at a rate to sustain flammability. The laser beam is introduced parallel to the injector face plate passing through the fuel and oxidizer mixing zones igniting the propellants. The propellants are ignited by having a laser beam tuned to a frequency to excite the oxidizer such that it will chemically combine with the fuel to form an ignition kernel in the flame holding zone. When a plurality of injector elements are ignited in this manner a controlled ignition process in the combustion chamber is achieved.
