I can't see = how the laser would ever get dirty.  The entrance to the combustion ch= amber would be covered by a lens.
There would be no need for the plug ho= le that allows conveyance between chambers, and the apex seals would contin= uously
be wiping it clean.  The electronics would all be solid stat= e, and the only requirement would be proper cooling.
Designing for high = temps is old hat, but a little more expensive than what you find in consumer electronics.  Only a
coup= le would be required per engine, and if designed properly, would never need= replacing.  Best of all, the laser could
be situated so that it sh= ot a beam from one end of the chamber to other or across the chamber, ignit= ing a flame front
that is a line instead of a point source.  This o= ffers the possibility of creating the swirl to get at the fuel that is
h= iding in those crevices next to the apex seals.  Get that to burn and = the power and fuel efficiency goes up, exhaust
heat and noise go down, a= nd it becomes an even better airplane engine.
