260W IR Laser pump handheld?

[Borislav@87]

I received the 500W pump today. From what I see, I will need to drill the outlet here too.

This 500W pump is different from the one in the video. I opened it and there is a difference in the fiber grip. Fortunately, there is a hole and I may not have to drill further. I removed the metal part with the lenses and the fiber. It turned out that the two lenses after the cube are glued to the metal part of the fiber. This is good because I will not have to break them. I can't test it right now because I am not at home. I will write when I do. This 500W pump is definitely very easy to remove the fiber.

I wish they had a reason to mass produce visible arrays like that.

Yes, it would be nice to have such pumps, blue, green and red. If these are blue or green emitters, I can imagine how bright the beam would come out.

What do you advise me to use to power the 500W pump? Two 5S1P type 26650/5000mha batteries connected in series at 42V and 100A BMS with a 1800W boost converter that can output 22A current when the pump requires 24A for maximum power. That is, I will not have maximum power. The other option is three 6S1P 26650/5000mha batteries connected in series at 75.6V with a 40A BMS, using a step-down converter that can output up to 50A current. In the second case, I will easily get 24A current, which is required for full pump power. I will also have much less loss in the second option and the load on the components will be much less. For the 500W laser pump, I will use a larger box and there will probably be plenty of space for both options.

What do you need..... 42V @ 25A

Make sure to get one like this with constant current pot.

Pardon Our Interruption...

I have the same 1800W inverter. In this case, its input is 40A, and it can only output 22A.
This step-down converter would be easy to handle. The question is that I will have to find a battery 3x25.2V=75.6V (3x6S1P connected in series)

How powerful are the red diodes?

better put green or if it's red it should be 50mw

Green? Didn't you write that you were supposed to get the more powerful red ones? Why green and 50mw?

I ordered red and green. I'm still waiting for them. The green one is much brighter than the red one and is much more visible. That's why green is best in my opinion

You're right, green catches the eye more.. I can't wait for the next project to be ready, I even asked you something but you never answered me, in one of my questions on page 7

wearing IR safety glasses, you will know.
