While neutral, the cells are transparent."... Oh, hmmmm... The Pockels cell not work at this way! It never turn into a mirror. It just rotate laser beam 90°. If you carefully look at the picture of the laser assembly, you may see two Brewster platess. One of them serve as a mirror when injected beam income to the main amplifier, then this beam is rotated 90°. Such new polarization is allowed to pass through Brewster plate as through a window. After four passes, Pockels cell rotate beam again 90°, and then Brewster plate act like a mirror, so laser beam is reflected and exit to the next stage to the right on this diagram. My two cents.

I agree that LLNL, and all of the National Labs for that matter, are doing some really fantastic work. My department has had a project at LLNL for the last few years. Apparently they have some really terrific groundwater contamination issues, spilled jetfuel and who knows what else (I'm not personally on this project, either). If you happened to click on the Google Earth placemark (which, btw, the NIF is clearly visible on the LLNL campus), or since you've visited there, you know that it is smack in the middle of Livermore, CA. So, cleaning up the groundwater is something they are investing millions into. Bruce,

Great post on this project. Engineers in my company have supported various parts of this and earlier laser fusion projects, but we can't really talk about it too much. I didn't personally work on these projects, but I did go one time to LLNL to do some training on our software, which is used to design and simulate the optics (LOTS of optics in these projects, and alignment is a nightmare!). They have a very pleasant campus-like atmosphere, and I joked at the time (late 80's) that it could be called "Megadeath University," though in fairness, there has been a lot more than just weapons development going on in Dr. Teller's old stomping grounds for many years. Lots of good, important work like this (which is not to say that weapons are unimportant, just not my favorite application of technology). -Bruce It’s hard to keep up with you, Anthony, and now you’re even posting in optics!

Laser fusion! I wrote a short essay about this last year, I’m glad to see its getting the funding it needs. Laser fusion!
