Hello. I have free time and decided to assemble a portable IR laser with a power of 260W. For this I will use this laser pump which needs 29V and 18A power. This is new to me so I'll probably need some help. I also ordered a compatible lens that mounts on the array and will probably have...

First test of the lens from Aliexpress with 1250mm focal length. I am very pleased with the result. https://a.aliexpress.com/_EIcit6N

I had bought these drivers a long time ago for a test. This one is step down 5V and 5A. In a test with two 18650 batteries to a damaged NUBM0F laser diode, the driver put out 4.3A and held them steady. I didn't feel it heating up. High Efficiency Output 3.3V 5V 9V 12V 5A mini560 Step Down...

NUGM04T (2.7A) 2W NUBM38 75W 4A (Probably around 100w)

NUGM04T after one year of use. I had previously read opinions that decaned diodes have a short life. From my experience I have 2 decaned diodes NUBM0E and NUGM04T and still work perfectly normal. The green NUGM04T was used the most. It works at 2.7A and outputs 2W of power. Its power is the...

I received a NUBM37 125W laser array yesterday. First I rewired it from the board to remove some of it and break all the circuits with the pins. Currently, each pin is independent. Previously, 2-3 pins were connected and making a connection. Now everything is broken. I'm using the board for...

Hello. I came across this seller on Aliexpress and noticed that the laser array prices are very good. They may have been used, but I can't tell. If the topic does not follow the rules, please remove it. I have nothing to do with Aliexpress. Just found this amazing item on AliExpress. Check...

Hello. Winter is coming and I'm starting another project. This time I decided to make a laser gun out of a screwdriver. I bought a new battery 20V/4Ah, body damaged screwdriver. I will be using the same 600w boost converters that I used for the previous such laser. This time instead of a...

A laser in an electrical box. The summer season will be used for advertising purposes. It will probably work every day for about 4 hours without interruption. 3.5A - 6W power

Hello. I'm wondering if there are any good drivers for this 8W infrared laser diode? I have drivers that I use for blue lasers but they run at 5V to 6A and this one says it runs at 2.4V and 8A. My driver specification Laser Diode LD Driver Board PCB 4.5A for 3.5W NDB7A75 3 Modes High Low...

Hello. I am considering making a portable 75W laser. I am not very familiar with what I would need for this. The laser diodes that will be used are NUBM35 74W. The driver that will power them will be the one in the picture because I was told that it is suitable for this power. I will use 8...

Hi from a video on YouTube, I made an LPM meter, which is very close to the real power and I can say that it shows very accurately. The price is very low and I think that everyone who is passionate about lasers should have something similar in order to be able to measure the power of their...

Hello. I'm posting a separate topic here if anyone has a similar problem. I bought a G8 lens for my custom laser, but the lens barely held because it made a good spot at just one turn of the thread. She was swaying and would fall at any moment. What did I do in this case. I disassembled the...

Hello, I want to show you my first custom laser that I made with a NUBM0E diode with a power over 6.5 watts, the laser is very powerful. I recorded a video of burning various objects. I expect the G8 lens to arrive. Laser diode NUBM0E 6.5W flashlight Host Manta Ray 8.2 (Long) LASER Diode...
