It’s a MAX photonics 280w pump source

I wanted to see what it looked like from above. Mine is with screws. I took them off and used a screwdriver to pry open the cover because it was stuck, but it wasn't hard. I had the hardest time removing the fiber from the front

yeah mine has screws but i think its epoxied on. i unscrewed all of them and its still stuck on

Mine was stuck too. I opened it with a sharp screwdriver. Go bold. You should remove it anyway

И ъъъ, как сложи червения лазер и извади влакното, това не мога да го разбера

 

[Nickguy]

im gonna uncuple the fiber pigtal from the pump

 

[Nickguy]

ok i got the top off

 

[Nickguy]

i think im either gonna burn the fiber all the way for fun or just cut it off

I put everything in the box for a test run. Space is quite limited. I'm thinking of putting two of those 600W (60V/10A) drivers connected in parallel, setting them to 30V and 9A. That way I'll have the option to include one or both together. That is, I will have an option for 50% power and 100% power.

Be careful with the fiber because if it's all the way down and catches fire it will stain the last lens inside if you decided to leave them on. Can you upload a picture so I can see what you did?

Oh wait I didn’t burn it all the way I just burned it into the ferrule, how did you drill a hole without getting dust inside?

I put brand new disposable nylon bags inside. They are soft and can't hurt anything inside. I also put tape in front of them. That way all the shavings were at the front. Be very careful what you drill with. I drilled it on a lathe. That way there is no chance that the drill bit will suddenly go inside and break something. It was very difficult for me to drill through because in the center along the fiber there is something like very hard glass or whatever material it is. I don't know how it is with you, you never uploaded a picture so we can see what you are doing.
