Sorry...I can't see anything in that tiny little pic.

Hi,
Looks like a 12mm module , if I think what they are made of it's a brass module with a chrome finish. If that is what it is then I wouldn't use it for a NUBM44 diode I would opt for a copper / 12mm module for a 9mm diode . copper is better to transfer heat to the primary heat sink.

You could drill it larger if you think your diode pins wouldn't fit, but I agree with Rich, I'd use a solid copper module with the optional solid copper back side available from DTR's store.
If you have more room, you could also look into one of DTR's 20mm or larger copper modules. :yh:
Be sure and put heat shrink tubing on your diode pin/wire connection no matter which route you take.
Your best option for an unlimited duty cycle is lab hosts. With active cooling you should be able to use them for both diodes. Since the divergence of the NUBM44 is horrible, you will have to use it close for cutting. This will give you another problem as you will have to blow away any debris and fumes or they will contaminate your optics. The closer to your material you need to cut, the great your power density of your beam will be. That means you will need a lot of air flow to push your cutting detritus well away from you laser.
