一种坚固的、小型化的、二极管泵浦的高能掺钕钇铝石榴石（Nd:YAG）激光器，其无源q开关在3ns下产生25 mJ，重复频率高达150 Hz。该装置是为内燃机燃料空气混合物的点火而设计的。泵浦二极管和珀尔捷冷却集成在激光头，给了一个紧凑的设计与少量的光学元件，便于组装。该激光器作为光学火花塞在测试发动机上成功地在高温和振动水平下运行。
A robust, miniaturized, diode-pumped high-energy neodymium doped yttrium aluminium garnet (Nd:YAG) laser with passive Q-switch generating 25 mJ at 3 ns has been demonstrated at repetition rates of up to 150 Hz. 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.
