Bryan;
There wouldn't be any need for "sweeping the beam" if a cylindrical lens
is used; it would generate a fan-shaped beam but the power density
requirement would probably be pretty high to initiate combustion.
Explosive charges can be triggered by a laser pulse transmitted in an
optical fiber so I guess a fuel/air mixture could, too. Finding the
optimum laser wavelength might require some investigation.

That's basically it Keith. We won't know how well it will work until
it's
actually tested because the combustion chemistry is so complex.
