Highly brightness giant-pulse laser induced breakdown ignitions promise to enhance the performance of internal combustion engine. It makes possible the ignition at the optimal spatial point apart from the cylinder “cold wall” with multipoints and multi-pulses. Giant-pulse lasers can fire leaner or high-pressure mixtures that are difficult to be ignited by a conventional spark plug and thus the fuel is used efficiently, while low CO2 and harmful pollutant emissions are expected. Unfortunately, the giant-pulse laser ignition has been limited the basic researches until recent progress of micro solid-state photonics. In this review, we'd like to discuss the progress of laser ignition system based on the micro solid-state photonics progress, and further giant micro-photonics for innovative ignition.
