If a Ti-B cannot survive, might as well forget about other lasers... Besides, Ti-B comes with other wavelength, if DPSS is not suitable, then choose other wavelength for your Ti-B.
Yes, but WHY would you want to try out with an expensive TiB when you can get a decent power newwish pen for a proof of concept?
As for other wavelengths, 405nm would be too dangerous at sufficient power to be seen.
445nm could work, maybe although blue does not offer enough contrast during daytime, so again a lot of power would be needed, also there is the issue of divergence... at 600 feet the dot wouldn't be nearly as much of a "dot".
For night time, even a 5mW red keychain would work great.
Daytime is really more of an issue, and leaves green as the only choice.
