We investigated the influence of the spherical aberration on ignition performance owing to laser beam focusing. Although ideal optical elements can produce a perfectly converging spherical wave-front, the spherical aberration of actual optical system results in a complicated intensity distribution around the focal point, which should significantly affect the laser-induced ignition of a combustible mixture. To clarify this, laser-induced breakdown in air with actual lenses was studied experimentally and numerically. Variations in the breakdown threshold and focusing profiles of the laser beam were investigated under various focusing conditions. We found that considerable influence due to spherical aberration existed in conventional laser-induced breakdown experiments. As a result, the focusing optics should be taken into consideration to minimize the effect of the spherical aberration in performing precise laser ignition experiments.
