From: Resonant dual-pulse laser ignition technique based on oxygen REMPI pre-ionization
Left: Pressure traces due to dual-pulse REMPI ignition of propane–air mixtures. The different curves correspond to different equivalence ratios. Right: Combustion efficiency for 3 cases of laser ignition of propane–air mixtures: dual-pulse REMPI (red), non-resonant dual-pulse (blue), and single-pulse NIR (black). Each point represents the average of at least three tests and the error bars are ± 1 standard deviation.
