What the heck is it called? Custom or a brand name?
It's a well known brand but I probably shouldn't mention it because I'm not sure I was supposed to do what I did... lol.

Do you know what kind of blocks are these? I see each has a driver circuit and all LDs in a block are probably connected in series, but were there any stickers on them like on this picture:
New Nichia 450-460nm Blue laser Diode module 8*3.5W /28.5W NUBM05 | eBay

Red, your link is 6500Lm.

Is there anyone rich and risky who could look inside of this PJ? (It might have new Osram PLPM4 450 chip inside...)
Epson Ls 10000 | eBay

or is thinking to buy a chip there:

Yes, you are right, there is no driver but I was just using words that chinese ebay sellers use in their item descriptions.

At least this board could save us some soldering.
But I do not get why are there 4 contacts, are 2 of each the same or can two 4LD arrays be driven separately? These apparently are all 2 pins LDs.

Can this be a kind of temperature sensor connections?

I think they are connected in two parallel pairs to decrease resistance and allow more current to flow.
