High Peak Power, Passively Q-switched Microlaser for Ignition of Engines

The compact (electric spark plug size), diode-pumped, passively Q-switched Nd:YAG/Cr 4+ :YAG microlaser was developed for ignition of engines. Output energy of 2.7 mJ per pulse and 11.7 mJ per four-pulse train with a pulsewidth of 600 ps and an M 2 value of 1.2 were obtained at a pump duration of 50...
