Very nice new footage
I visited the Utrecht University Sol exhibit, featuring the 7 lasers beaming onto the dom tower. To my surprise, we were allowed into the room where the lasers projected from - the window glass was removed against reflections.
Nice thing is that we got a good look of the freezer-sized laser units they used. Also, i had a bit of a chat with the German guys running this show, and they popped out a laptop to show me some photographs of the inner workings and diagrams of the conversion specifics.
It turns out that they used a sophisticated process of subharmonic addition to obtain wavelengths like 442 and 628 nanometers. Seeing these up close is simply amazing, and the engineering on these units is extremely advanced. Too bad i did not get to take any of the information home with me, but i can testify its well beyond anything we see here. If you're interested, the production cost of these units was in the order of $200.000 each, but they are no longer made as mobile units due to alignment problems with moving.
Anyway: Check out these pictures: Photos of LaserFabrik Utrecht II - Equipment and beams - Merghart.com - its probably something you'll never see again. And for those living in/around holland: The lasers can be visited between 8 and 10 pm until saturday.
