I'm wondering if you are using mirrors typical for CO2 lasers or a 
traditional optical?
My experience is with higher power and tunable dye argon lasers but the 
CO2 lab
used to use these front surface mirrors.
I just looked this up:
and what was interesting was that many of these high power mirrors are 
just polished
metal slabs with an IR coating (helps to prevent oxidation I would 
assume as well).
If you can connect with a DIY astronomy group, you might luck out and 
find someone with
an evaporator who coats mirrors and might be able to do an IR coating 
for you.
