OhioChief, you may not find the IR lasers to accomplish the task for which you want then.
I have used a Luna Optics and Dipol IR laser illuminators that are collimated and can focus down to a pinpoint like laser sights. They are also varialbe power and can be turned down quite low.
What I have found that happens, however, is that when the beam hits the fur of animals, it disperses and spreads amongst the fur. The result is that instead of having a paricular point illuminated, you end up with a baseball or larger bright glowing spot that is overly bright and makes it hard to see the area around the the glowing area. The result is that it makes it hard to actually place your shot on a particular exterior spot of the animal. You know you are on the animal because of the immediate and glaring bloom of light in the fur, but not very precisely where you are aimed.
The bloom and glares because of the spread of the light amongst the hairs and the return of the laser from countless reflections amonst the hair back to the NV gear. I believe the terms for the reflected light are scintillation and chatoyance.
This has been my experience in trying out sighting on hogs and testing with hogs and well as deer and raccoons as surrogates (none shot, of course). I do not think, based on my experience, that you are likely to be able to make a properly precise shot, a humane shot, using an IR laser on furred game with NV gear.
With that said, I would be interested in hearing if you do find a successful option that works. If you buy an IR laser to test, make sure you can return it if it doesn't work as desired.
