260W IR Laser pump handheld?

[Borislav@87]

Yesterday I managed to connect all the cables. I also glued a protective glass on the laser. This way, dust and moisture are impossible to get in. All that remains is to get the BMS for the battery. In most places I use chemicals instead of soldering.

How do you take the lid off the laser arrays without screws?

I rubbed my 120W with a file until a crack appeared and then opened it like a can with a small screwdriver.

 

[Borislav@87]

I will also have to add a diode to each of the output drivers, because when one driver is turned on, it injects reverse current into the other.

I might have to remove the lenses to focus the laser into the fiber so I get a collimated output

 

[Borislav@87]

I bought these diodes from a nearby store. The small ones are up to 10A, the big ones are 50A. They must be installed because if only one driver is turned on, the fuse of the other one burns from the reverse current. If both are turned on at the same time, there is no problem.

How did you drill the hole my dremel is struggling very hard

Nickguy,
Why can't you post pics? Do you need 20 posts?

 

[Nickguy]

did your laser diode have ceramic where the hole u drilled was?

Nickguy,

it says the file too big even tho its just a pic

 

[Borislav@87]

did your laser diode have ceramic where the hole u drilled was?

Yes, of course it was ceramic and that's why it's very difficult to break through. You take a screenshot of the picture with your phone and upload it.

Maby someone will chime in to help.. I have no idea.
Its pictures your taking right? I only got the message file too big on videos I trried to send which was limited to only 5 seconds but I use a cheap flip phone.

Stupid question on my part, have you tried changing the picture size or resolution?

Drilling ceramic--Try using a Dremel 562 Tile Cutting Bit or a diamond drill bit.

Photo size: Google "how to reduce the size of a digital photo"

How old are you?

PS Borislav told you twice how he drilled a hole--post #60 and #71. If you don't know what you are doing and don't have any knowledge, skills, or tools, why are you attempting to copy Borislav's project and work?
Do you just want an invisible laser that is very dangerous for your eyes and the eyes of any other people exposed?

 

[Borislav@87]

This laser is very dangerous and powerful. It is mandatory to install another visible laser to see where it is pointed. It is also mandatory to have a secret access key. I personally very rarely play with lasers. I am more interested in assembling them. After I assemble it and everything works as it should, I will write everything in one post about what and how I did it. I have an old camera, on which I plan to remove the IR filter from the matrix and capture the light from the pump. Or buy a budget camera with which I can capture it
