Hey laserpeeps,
After lots of good conversations with laser enthusiasts, they have convinced me that with my budget and what we are trying to do, its not going to be possible rent anything with enough oomph.
We have decided to build some stuff, and learn along the way, like children
With that said, we are buying some stuff from DTRs site, and going to go from there. Hopefully I will get the second part of the grant, and we can do more.
I will post on the green and blue lasers, I assumed 1.5 mrad, and 3mm beam diameter. Can someone double check my calculations and perhaps run them through skyzan?
I'm still learning and will be happy to take your ribbing hehe.
Regards,
Wally

Green laser calculations
SZED (flashblindness distance) in feet = (32.8 / milliradians) * (square root of (12.7 * milliwatts * VCF))
CZED (glare distance) in feet = SZED * 4.47
LFZED (distraction distance) in feet = CZED * 10 (this is the same as SZED * 44.7)
Typical Visual Correction Factors
Green 532nm VCF = .088016
Red 633nm VCF = .23825
Blue 445nm VCF = .03050
