Application of laser ignition to hydrogen–air mixtures at high pressures
TLDR
In this article, a Q-switched Nd:YAG laser at 1064 nm with a pulse duration of about 5 ns was used for ignition of different hydrogen-air mixtures, using different filling pressures (p=0.5-4.2 MPa ), different ignition energies (pulse energy PE=1-50 mJ ), different chamber temperatures (T=393-473 K ) and different focal length lenses (f=60, 120 mm ).About:
