Quoting wikipedia:
Seeing that we're starting to have an abundance of UV lasers with the recent addition of Frequency Quadrupling, it maybe be worth looking into Osmium as a Mirror or Focusing Mirror in Lasers.

Forumite: qswitched -sama, add Osmium as a thermocouple material so our ludicrously overclocked reactors that will meltdown in six months can POWER MAOR LAZORS!1!1 Qswitched: Sure. Forumite: qswitched -sama, let us stack frequency doublers so that our deathbeams become even better! Qswitched: Um. Okay. Forumite: qswitched -sama, let's combine the POWER OF OSMIUM and FREQUENCY QUADRUPLING for MAOR LASER POWER! Qswitched: *Sigh*

How is its reflectivity in the visible range? That may be a bigger difference than on the output.
Also, obligatory suggestion for dielectric mirrors (or just layering different refractive indices in front of a poorer mirror material).

Is it better than aluminum at UV range? Because that is the dominant mirror material. For all other components, you would be looking for good reflectivity in the IR range.

Brief look on Wikipedia, comparing the reflectivity of Al/Au and the claim of Osmium having "twice the reflectivity of gold" suggests that it won't be so great compared to aluminum.

It may depend on the spectrum, maybe they are looking for reflectivity in spectrum where aluminum can't do, or where aluminum or melt. Here's the thing though, within the laser cavity you're looking for good reflectivity in IR range, cuz that's what the lasing medium generates. At the output mirror you're looking for good reflectivity at your output range, which these days in mostly UV where aluminum is best. It's possible that Osmium is good at reflecting UV, better than gold but not as good as aluminum, in which case it wouldn't be useful in lasers until melting temperatures for sub-components are implemented in game. To be useful otherwise, it would have reflect IR better molybednum.

COOL! well, I guess you could call X-ray lasers "Xraysers"
