Abstract
To develop a new ignition method, we carried out a series of experiments on ignition with excimer and
Nd:YAG lasers. When we use an excimer laser, we can produce radicals in the focus point that advance
the mixture’s ignition reaction. When we use a Nd:YAG laser, the focused giant laser pulse induced
breakdowns in the mixture. In both cases, the laser ignited the mixture. In this paper, we show some
results of our laser ignition studies from the past 20 years at AIST.
