also the chamber causes photons to accumulate and bounce around, which makes a lot of lag. Thin line of pcln surrounded by void except where the beam comes out. also it doesn't need to be continuously sparked by pscn, just once.
Photons aren't emitted in random directions, so you only need a long, thin line of pcln to make a beam. The 'chamber' on this is pointless. Only the p ln that is lined up with the exit is being used.
yes, pcln is transparent to PHOT so it's not just the surface making PHOT like normal CLNE. Much stronger beam
