    260W IR Laser pump handheld?

    There is enough information in the forum. Actually, there is nothing for me to teach you. Ready-made parts for lasers are sold. In all my lasers that I have made, I have used a lathe to make the radiators where the diode goes. This is not so simple.

    260W IR Laser pump handheld?

    24 emitters in total. Each one at full power will produce about 20W of power. 500 divided by 24 = 20.8W of power

    260W IR Laser pump handheld?

    For this 500W, the battery is important. Given that I will use an inverter, I will need a suitable BMS. It is good to have at least 20-30% reserve. In this case, 25.2V with a 40A BMS will not be able to handle 45V and 22A operation. If the BMS is 25.2V 60A is ok. But I have a 6S 40A BMS...

    260W IR Laser pump handheld?

    ChatGPT calculated for me what power I will achieve with these amperages. The 1800W boost converter says it can output up to 22A. But it will probably be able to output 23A, because so far all converters output higher voltage and current than described. So if it outputs 23A I will put it in. But...

    I have 25 new Litokalla 26650s. I will make batteries with them

    260W IR Laser pump handheld?

    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

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

    260W IR Laser pump handheld?

    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) https://a.aliexpress.com/_EQXGvWW

    260W IR Laser pump handheld?

    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...

    260W IR Laser pump handheld?

    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.

    260W IR Laser pump handheld?

    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...

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

    260W IR Laser pump handheld?

    At 15 meters it won't pierce this tree. From what I've seen, maybe up to 3 meters I can get a good focus for piercing. After that, the beam expands and can't pierce, but it can easily set things on fire. I'll see how the other 500W one is when it arrives. They say that if a fiber is used as a...

    260W IR Laser pump handheld?

    If you're asking if I can adjust the focus. Yes, I can with both lenses. With the larger one, I can get focus from 2 to 15 meters by rotating the front part.

    260W IR Laser pump handheld?

    Yes, this lens is different. With it I get the closest focus for burning. Accordingly, its power is the greatest, because the focal length is small. With the other one I get focus after 2 meters, while with this one I have focus at about 30 centimeters
