Operation at high temperature of a diode-pumped passively Q-switched Nd:YAG/Cr4+:YAG laser

Abstract

Compared with a conventional spark-ignition system, a laser-induced ignition of air-fuel mixtures in internal combustion engines presents many advantages, such as a higher probability to ignite leaner mixtures, no erosion effects, increase of engine efficiency, or shorter combustion time [1]. However, a laser used for ignition has to withstand hard-working… (More)
