A fan from a computer will not do. It will be too weak if the radiator is small. This one is super powerful and I guarantee it will handle even a small radiator. I use these heatsinks and they work great with this fan

Yes, you have to remove all the stuff on the board. This driver says it's 4.5A, but it's actually 3.5A. It can easily be modified at what amperage to run by changing resistors. It has a soft start and three operating modes. The driver is very good and stable.
Hello. Now I see what you wrote. The driver who is on the lantern must remove all the element and destroy it. You just need a pair of pliers and I remove all the components with it. Then I solder the minus and the plus. This converter will do the job, but you won't be able to use it because...
I don't know exactly how this host is built, but I've taken apart off-the-shelf lasers and it's not that easy to take apart without damaging anything on the driver and diode. It wouldn't hurt to upload a few pictures to better see how to take it apart.
I don't have that much experience and knowledge in this field. I just have experience with certain diodes and have used a variety of converters so far and have had no problems with any of them. Yesterday I mistakenly ran 4.7A on a NUGM06 green diode and it is alive after that. I have set them...
I have experience with blue NUBM0E at 3.5A with driver from Aliexpress. They light up without problems for 5 hours without interruption. Of course with fan. My point is that modern diode
last a lot longer than years ago. I put 5 seconds of 7.5A on NUBM0F and it is alive. Poor cooling is...
Okay, I understand that you follow what's going on too fastidiously. But what negative effect will that have on the diode when most people use laser pointers for short cycles. I have tested all kinds of converters from Aliexpress and they all work very well with laser diodes. None were damaged.
I can not say. Apparently it needs to be reprogrammed. Personally, all three modes are good for me. You have a weak impulse mode, with fast movement it gives an interesting effect. A blinker is a blinker. The power is smooth, as in the beginning, and is slightly impulsive, as in the weak
Keep in mind that these drivers are actually 3.5A, not 4.5A as it says. I modify them to 5.2A by replacing one transistor. Actually, I can modify them as I see fit. I can make them 6A, 4.7A, 2.8A, etc. You just need extra of those little resistors.
R100 + R620 +R500 = 2.86A
R100 + R750...
Just yesterday I made two P4000 single mode driver lasers and they are very easy to work with. I turn on the turbo with a quick double push of the rear push button (without turning it off). For me, on turbo, it takes out 5A without problems. I use Litokalla high discharge batteries. I also...

It is, but the NUBM0F can withstand up to 6A without problems. Especially for him, I see no problem working with this driver. In this case, 4.2A is nothing for this laser diode. I doubt it will damage the diode because 4A is quite far from the maximum it can handle. My 7-8W...
