I picked up one of these for $25. I designed and 3D printed an adapter for one of my standard hosts with an NDG7475 diode and it works great. The Beam Expander shrinks the spot to a very small point. I was only able to test at about 100' but it could certainly go much farther. There's probably some power loss from the slightly mismatched wavelengths but not enough to notice without putting it on my LPM.

Sweet, did you cut your threads or were you able to print them ?

I just print them and they come out perfectly.

FYI - Everything after the ? in a link is just for tracking purposes. I usually truncate links I post so they don't look like this. The Chinese are tracking the $hit out of you with those links....
This works just as well:

I just moved a couple posts from here into the General News Discussion Thread to avoid a derail. Feel free to discuss that sort of thing, but that thread is a better place.

Unfortunately the G86 is only rated (by Mitsubishi) for 3.8W pulsed, 2.1w CW operation. Still a lot of power, unfortunately divided between 3 beams.

Typo perhaps? I see a 558nm DPSS module, looks to be the same ones used in the recent crop of "561nm" pointers. Mine spectros out at 559nm

They just keep getting even more powerful!

EDIT: on closer inspection it looks like they just stuffed an extra LD on each of the four rows for the extra power over the NUBM37 (125W)
