Abstract
A robust, miniaturized, diode-pumped high-energy neodymium doped yttrium aluminium garnet (Nd:YAG) laser with passive Q-switch generating 25mJ at 3ns has been demonstrated at repetition rates of up to 150Hz. The device is designed for ignition of fuel air mixtures in internal combustion engines. The pump diodes and Peltier cooling are integrated in the laser head, giving a compact design with a small number of optical components for easy assembly. The laser was successfully operated as an optical spark plug on a test engine at high temperature and vibration levels.
