Default Just out of curiosity is there a max temp rating for a NUBM44 ?

Does anyone know what temp should you not go above with a NUBM44 diode ?

I noticed that the diodes in Sanwu pockets seem to get on the warm side and they still work. I do push mine quite hard because their not all that expensive so I abuse them a bit. The 044's are a good tried and true diode ( in my opinion ) so I push mine pretty hard also. So "how hot" how brave are you?

Ps. didn't really answer your question did I ? Oooops

Default Re: Just out of curiosity is there a max temp rating for a NUBM44 ?

Ideally you want to keep the operating temperature below 60 degrees celsius.
I'm trying to locate a spec sheet, but 60 degrees seems about right for the operating temp. The storage temp usually is higher by 15 degrees or so.
You don't want to exceed the max temp as the worst case scenario is a thermal runaway.
Does anyone have access to a NUBM44 spec sheet?

Default Re: Just out of curiosity is there a max temp rating for a NUBM44 ?

You're welcome. I still want to locate the appropriate spec sheet to be absolutely sure. But 60-65 degrees celsius is the average for most diodes. Although the NUBM44 is by far not an average laser diode.
For best lifetime you really want to sit around 40-45 degrees celsius max.

Default Re: Just out of curiosity is there a max temp rating for a NUBM44 ?

I cannot find a spec sheet when searching, probably isn't one but if someone comes up with one, you get a hug from me. I checked some other laser diodes at that wavelength and the 60 C figure seems conservative enough to me, but to add some margin 50-55 C max is the most I'd run it at. That is actually quite hot when converted to F, 55 C is 131 F., hot enough.

Yes, a spec sheet would be most useful. If your laser is getting dangerously close to 60+ then you need to adopt a sustainable duty cycle and/or improve your heatsinking/cooling.

Oh no I'm not getting anywhere close to that, Up around 110f is about the highest I've gone and that was after minutes of continuous running.

Man I really like this 44 ! You should see the dead ceiling fans wooden blades and the wooden lamp across the room, They both look like leopard skin with all the large black spots on them, Plus my room smells like I have a wood stove in here ! LOL

Yes, it is a unique and dangerous laser isn't it. I can smoke wood within the time it takes me to flip the switch on/off at the plug. Be careful, I did a video as a warning to show how quick it is. You can easily burn your house down for real with this diode.

I think it might be quicker at setting something on fire than if you used a torch, I'm not kidding !

If it's pre focused you just point it at something and most of the time "poof" and it's flaming that quick ! Point it at something else and "poof" now that's flaming !

Thanks Encap. Yay, I was correct with 60 degrees celsius.

Accutronitis, I have this laser on camera burning through 20-25cm of styrofoam in 12-13 seconds.

I don't have a lot of experience with this yet but this thing is such a monster I'm kind of surprised it takes that long !

Default Re: Just out of curiosity is there a max temp rating for a NUBM44 ?

I get mine good and warm, sometimes I open the icebox and roll the heat sink around carefully melting ice to cool it for more runtime.

BTW

I have been putting little volt meters on some of my builds and adding them to older builds, they are accurate as verified by my fluke meter.

Anyway the only 2 cell NUBM44 I have left, that is the only build I have not upgraded to 3 cells is running 2 cells and they sag much faster, as the cells wear out over many dozens of cycles they sag faster, also switch springs get weak and you can see voltage sag with orientation, you would be surprised how hot your tail cap spring gets where it makes contact with the battery.

If you want full power out of the NUBM44 you have to feed it.

This is why I feed it straight from the mains.
Constant power, better heatsinking. Better overall.
