Your point makes this sound like a false claim.

I am not saying it could not be done but it wouldnt as straight forward as a in a gasoline engine where you could unscrew a spark plug and screw in a laser plug.
In a diesel you would have to remove the cylinder heads to machine a new port for the laser to be fitted and a new timing system to fire the laser. Diesels do not have ignition systems because the heat of compression ignites the fuel air mixture not spark plugs.
And I am sure there are a lot of other details I am not thinking of having never worked on a diesel.
