Is molybdenum a better mirror for a 75W CO2 laser?

They look like they carry inventory and in California, close to me.

The have ebay store but of course, most of this stuff comes from China I suppose.

Andrew,

On other forums a lot of US/Canada Guys buy from Lightobject (in preference to ebay direct from China) to avoid import problems and shipping damage (especially tubes). They consider it is worth the slightly extra cost and so far I have not heard a bad report about them.

Hope this helps.

You would see zero benefit (and probably some loss since it has a lower reflectivity to near-IR compared ot gold) in going with MO mirrors. They're designed for high-wattage systems (think multi-kW) where backsplatter needs to be cleaned off of the mirror from time to time. Your mirrors are not in a position to see backsplatter, so the durability is wasted.
