Dan,
This used to be a joke, but it is remarkably accurate...now. I might not even need to make my own video. The concept of a frozen singlet state was one of the avenues I actually pursued for a while, but 4 nsec to 6 nsec isn't worth it. I also tried to use that refrigerated system to cool the dye to around 3C to take advantage of the unique property of water that completely eliminates thermal lensing. It works, but the efficiency is quite low; not worth it despite the incredible beam specs.
I have holes in numerous targets... and a few non-targets as well including one healed hole in my hand. That was sure stupid, but encouraging .
I am not going to continue to upgrade this system despite the ease of doing so. The optics will simply not permit it without going to really exotic coatings. That is just too expensive.
