Miniaturized passively Q-switched Nd:YAG/Cr 4+ :YAG lasers are promising candidates as spark sources for sophisticated laser ignition. The influence of the complex spatial-temporal pulse profile of such lasers on the process of plasma breakdown and on the energy transfer is studied. The developed measurement technique is applied to an open ignition system as well as to prototypes of laser spark plugs. A detected temporal breakdown delay causes an advantageous separation of plasma building phase from energy transfer. In case of fast rising laser pulses, an advantageous reduction of the plasma breakdown delay occurs instead. 4730-4739 (2007). 12. T. X.

“…In this context, laser ignition can be regarded as a very promising alternative. Many advantages of laser ignition have been investigated yet under laboratory conditions [1][2][3][4]. Beside a lower energy demand at increasing brake mean effective pressures, the lower ignition limit for lean mixtures has to be emphasized [5][6][7].…”

“…Laser ignition system has been under much attention recently for its many potential benefits, including the greater control over the timing and location of ignition, absence of electrodes and possibility to allow ignition in multiple locations [20]. Laser-induced spark ignition which depends on electrical breakdown at focal point of laser is descripted in [21].…”

Abstract-The spark and compression ignition principles of petrol and diesel internal combustion engines (ICEs) have not advanced for a century. These do not lead to complete combustion and hence result in high exhaust emission and low energy efficiency. This paper presents a comprehensive survey on the attempts and developments of greener ignition and combustion systems for ICEs and points out that homogeneous charge microwave ignition (

We have studied and developed a compact nanosecond laser system dedicated to the ignition of aeronautic combustion engines. This system is based on a nanosecond microchip laser delivering 6 μJ nanosecond pulses, which are amplified in two successive stages. The first stage is based on an Ytterbium doped fiber amplifier (YDFA) working in a quasi-continuous-wave (QCW) regime. Pumped at 1 kHz repetition rate, it delivers TEM00 and linearly polarized nanosecond pulses centered at 1064 nm with energies up to 350 μJ. These results are in very good agreement with the model we specially designed for a pulsed QCW pump regime. The second amplification stage is based on a compact Nd:YAG double-pass amplifier pumped by a 400 W peak power QCW diode centered at λ = 808 nm and coupled to a 800 μm core multimode fiber. At 10 Hz repetition rate, this system amplifies the pulse delivered by the YDFA up to 11 mJ while preserving its beam profile, polarization ratio, and pulse duration. Finally, we demonstrate that this compact nanosecond system can ignite an experimental combustion chamber.
