Paper Abstract

Laser ignition of internal combustion engines reveals a number of advantages. High-pressure chamber experiments with lean hydrogen-methane-air mixtures were successfully performed and monitored by optical Schlieren diagnostics. Multipoint ignition was tested for 2 and 3 ignition points with different separations. In this way, relevant ignition parameters were acquired allowing estimate future laser ignition systems. Transportation of high intensity 6-ns Nd:YAG laser pulses via photonic bandgap fibers with hollow core was investigated. Evacuation of the core for the first time allowed to increase the peak intensity of the propagating pulses far beyond the breakdown limit of silica yielding 600 μJ fiber output with single mode characteristics.
