You can use high powered lasers in short pulses to compress and heat a fuel pellet to achieve fusion. A particular approach called fast ignition requires a petawatt pulse. Given that the laser is named LFEX for "Laser for Fast Ignition Experiments", it is a good bet this is what it is for.
(My expertise in this is limited to having had an inkling which Wikipedia article to look in for the answer. Further input from real experts is welcome.)
Note, too: you completely ignored my procedural point.
I presume I am not one of the "usual suspects" - or if I am, you are getting no pleasure from me.
Oh, I already have, baby.
Furthermore your constant state of goalpost-moving - particularly the fact that you are able to support your team in part but anyone of any other team must support their team 110% of the time - is again noted.
Is that like when you try to typecast #OccupyResoluteDesk to "conservative", or do you have some other meaning in mind?
Not just a projected image, but anything it illuminates (so long as there is little other illumination to mess up the effect.)
If you've ever played with a normal monochrome laser in a dark room, you'll have seen how laser illumination makes things look speckly. Illuminating with this "white" laser will make superimposed speckly in three colours, with the locations of the speckles not coinciding, so it would be iridescent speckly.
