My own job and lasers, up to the 1-watt range? Yeah. We've met.
Don't read too much into what I typed. I've lost count of how many folks I've seen procure the things...without bothering to think about what they're going to use to see the damned IR beam. That's all.
If you have and use I-square devices, that's a different story, you've actually put some thought into it instead of just getting the laser because it's cool, which is the trend, not the exception. Lots of wasted $$$, there, on the difference between need and want.
Safety is another thing. I see whole reams of BUMED and other incident reports regarding laser incidents within the military, where a user is likely to get some sort of brief, even if it's bastardized and they sleep through it. Civilians...hell, show me a site with a specs listing that lists, much less defines, the NOHD of a Class 3R VISIBLE laser. An IR laser? "Well, if I can't see it, it must not be able to hurt my eyes (presuming that they know that lasers can burn retinas to begin with)."
That last, in my mind, is the reason for the mil/LE restriction, and while I know in my gut that it's probably too much of a blanket policy, I see too many permanently damaged eyes to want to see it lifted. There are idiots in the business world with vis-green laser pointers that are rated 3R and have an NOHD of 28m+, designed for use in large auditoriums, in a 12x15 break-out room with floor-to-ceiling windown and shiny wet-erase boards. No clue why that's A Bad Thing. It's even easier to be negligent with a beam you can't see.
Hell, part of it is also that the glamor of the things is lost on me; I can yank the things out of a cage by pointing and saying "Gimmie!" Matter of familiarity breeding contempt, I'm positive. The honeymoon's over.
