The circular things are slanted just to keep the input and output plane aligned with the board with the pegs, yet providing space for the correct length of rolled up fiber. This part of the machine must not tilt the fiber to much, thus giving the engineer two choices. 1. Build it linear (and end up with several meters of machine) 2. Roll it upp neatly somehow and dont mess with the axiss.

Your "Way more powerful" diode bars are nothing compared to good fibre lasers. The beauty of these things is single mode spatial output (pulse characteristics are also nice but not as unique) that lets you focus down to micron or less spot sizes. The relative increase in intensity due to this dwarfs anything big multiomode emitters such as a diode array could ever achieve with their limited focal size. All that said this looks like it may not be strictly single mode fibre, should have got an end view shot of the output fibre from the splicer (the fact that you can change the mode shape by adjusting the fibre position indicates this). If that is the case any incorrect bend in the high power fibre section will decrease or even destroy your beam quality. Alternatively the output cleave / AR coat before the isolator might be bad. Also the copper tape is likely just a beam dump for unwanted low power light.

You still need a cleaver to cut the fiber. Possibly 2 depending on the spice. Active fiber is octagonal in shape and needs a special cleaver. Other splices like the pump combiner use simpler cleavers/splicers

Marco, you have been a huge influence on me getting into lasers over the past year. Now my electronics lab it littered with jenoptik and coherent laser modules purchased off eBay… All in different states of working or disrepair. I know it’s been a tough year....And I know you’ve been busy. But we could really use laser content right now. It doesn’t matter if it’s really advanced or really basic beginner stuff… we will be happy with anything! … but since “ Tech ingredients“, “styro pyro”, “zenodilodon,” and “ thought emporium” haven’t produced any laser content for months… We could really use your laser content to take our minds off the shitty year of 2020. Hope you are doing well!

I used a very similar model arc fusion splicer years ago when I was working for one of the major cell phone networks, splicing fiber in some specialty systems for big clients that required cell nodes on site. Those are some amazing machines. I never could figure out just how it manages to actually measure loss in the splice without sending any light through the cable. I guess it just evaluates the image from the cameras.

Perhaps the output head is also misaligned? You're lucky that this laser doesn't use the output fiber and head as part of the "resonant cavity"(ish). I believe some IPG lasers do that, in which case cut cable = paperweight laser, even if you manage to splice it back together.

I think there was a connection between Nortel or Sifam and Oclaro? (makers of the pulsed laser in yours). I used to do splicing for building EDFA (Erbium-Doped Fibre Amplifiers), which would have worked in a similar way to your laser, but nowhere near as high a power. lol That laser lab in Hanover looks awesome, too. Kind of wish I still worked with lasers. I have two 50-70mW Argon lasers collecting dust atm.
