Abstract
The output performances of a compact, passively Q-switched Nd:YAG/Cr4+:YAG laser were investigated using single crystals and poli-crystalline ceramics Nd:YAG with doping level between 1.0 and 2.0-at.% Nd, and single crystals and poli-crystalline ceramics Cr4+:YAG with various initial transmission. Q-switch laser pulses at 1.06 μm with energies up to 2 mJ and duration below 1 ns were realized at a pump repetition rate of 10 Hz. An all-ceramics Nd:YAG/Cr4+:YAG laser could be a solution for ignition of automotive engines. The optical intensity of a laser pulse with ns duration that induces optical air breakdown was determined.
