Well, this is the second one o these diodes with the same problem, the one I bought from another member and now yours. Why? Is this power level so high that if you don't get the beam focused right, i.e. the lens too far away from the diode light reflecting off the holder damages the window? This is a wild guess or stab at what is going on, if this is the problem maybe focus to infinity at low power, or maybe this isn't the issue? We haven't had high power diodes like this before, there might be something going on like this that lower power diodes aren't susceptible to. At first I questioned whether there was a vapor deposit of rosin on the lens from the extraction process, but if DTR is checking all of his to assure the windows are clean, that can't be it.
