I can't be sure if this is a clean window failing under intense light or a contaminated window failing where the clean one would not. The G-2 would probably not get splattered with window debris if the damage was a coating and some cracking. This sounds a little more like an organic contamination. The G-2 might have introduced some dirt when it was threaded in.
These really powerful lasers are going to introduce new problems with optics damage, thermal loading and beam correction.
