ANYTHING Q switched is IMHO an eye hazard, never mind a couple of kW average power Q switched, that is just adding insult....
I wonder how many video camera sensors they go thru making these videos? Those things don't much like laser up em either.
I have played with doing this sort of thing with an old arc pumped ex medical 'KTP' (Steve will know the machines to which I refer) butcherised into a 1064nm Q switched setup, I kept blowing out the OC, but it would sort of work at the ~150W level. Really need to get around to reworking the cavity on that to get the power density at the output optic down by an order of magnitude or so (No this was not a first pulse suppression issue, wise to that one).
I suppose I should try it with a 'greenlight' instead (Yes, contrary to popular belief you can get them to go without the card), at least you can see the effin' scary reflections with that!
OD7 or so, ANSI certified is your friend, that and wool suits with wool full face hoods (Wool because it self extinguishes and chars instead of melting, think marine firefighting kit).
Play safe, you only get one pair of retina.
