@Jay - That could actually be very good news.
Can you try one last thing.. and only if you can defocus the laser so as not to damage goggles... put goggles in the beam path in from of the lpm thermopile. See if LPM picks up anything. Considering the output it should pick up 1-2mW of green, anything else will be IR.
Usually when doing this I also move the goggles around in from of the sensor so as not to keep the beam on the same spot for any amount of time.
Lol, if you recall I was actually the first one to point to the specs on this thread... on the WL website. What they are doing though is VERY deceptive imho. If they advertised it as a >500mW laser instead, it would be a different story.
You're 100% right about kids not being able to tell apart a 300mW green from a 1W though, especially if all they have for comparison is an arctic, or other lasers from WL. Hell before I got an LPM and some more powerful lasers, I was pretty confident that the 80mW green laser I had was actually 150mW

I'm not sure you could consider it "under spec." After all, it is advertised as "500-1000mW" if you care enough to read the specs. We already know that the "1W" is just a maximum. WL's target demographic is primarily teens and young adults that have less than basic knowledge of lasers. They won't know the difference between 500mW and 1000mW of green light. Hell - you could probably give them 300mW and they would still believe it's 1W. :shhh:
And Jay, I second the IR test. In case you didn't notice, I suggested a couple more methods of testing to be sure of the IR content:
