ABSTRACT:
An ignition apparatus for a combustor includes a microwave energy source that emits microwave energy into the combustor, and a laser energy source that emits laser energy into the combustor so that a plasma is produced that ignites a combustible mixture therein. The plasma preferably is a non-contact plasma produced in free space within the combustor spaced away from with the combustor wall structure and spaced from the microwave emitter. In one embodiment, the microwave energy is emitted at a frequency within a resonant response of the combustor, and the laser energy is infrared laser energy.
