This is a "window" and the laser focuses in the middle of the combustion chamber. There is actually a cheaper way to do all of this using standard plugs. You have a small prechamber which has a mixture that is far easier to set off. This then fires the main chamber. Most of the emmisions occur in the prechamber. THe secret is making the prechamber large enough to get full ignition of the main chamber but keeping it as small as possible to limit emmisions. The large industrial engine manufacturers have been doing this for years. I don't think it has been economical on the smaller engines. CAT, Wartsilla, AJAX and Superior all use this technololgy. I'm sure the rest do as well, but I'm not familiar with their product lines.
