I received a NUBM34 from "Newgazer "on eBay. It was ordered April 29, delivered May 7, by FEDEX, no problem. The 24 diodes are mounted on the base plate, each has a bypass zener diode. A mirror, at 45 degrees, reflects the output normal to the face of the device.

I have limited the current to way below the lasing threshold so far. (220 - 420 mA ?)
I'm new at this, and don't wish to vaporize my eyeballs, camera, the device, or burn the house down.
17 v will light a row of diodes. On 18 v, it draws 1 mA. Some preparation is necessary before I can crank it up.
(Yes, I have good quality laser glasses, per StyroPyro )
