This is a most excellent place for technology news and articles.
Inertial confinement doesnt produce a "stable reaction" it is pulsed by it's nature, think of it in the same way as a single cylinder internal combustion engine, periodic explosions which are harnessed to do useful work. So no the laser energy is required every single time to detonate the fuel pellet.
NIF isnt really interested in fusion for power production, it's a weapons research facility that occasionally puts out puff pieces to make it seem like it has civilian applications.
Your take is incorrect.
It would be more productive if you said how you think im wrong. Just saying 'youre wrong' doesnt really add anything to the discussion.
