Hi All,
I've been sent a new source for 12x BR diodes so here are some pics and output info. It looks like it could be a, "New Kid on The Block". [EDIT: I won't edit the title as it may confuse but... It seems this may not be the BDR-S06J sled but the 10x sled from the LG drives posted here -
http://laserpointerforums.com/f38/hello-lg-bh10ls30-10x-47723.html
However, the figures still look pretty good. Of course there is not much known about how long they would last at the levels I tested at. No failures of either of these diodes during the test though and they initially look to beat the graph for the SF-BW512L 12x Lite-On diode I tested from the GB. Again, only preliminary results at this point. More examples need testing.]
The sled is, as the picture describes, a BDR-S06J, (at least in emails it's described as the BDR-S06J but I guess looking at the box it could be sold as a BDR-506J? It's supposed to be from a 3D player? Whether this will demand different characteristics from the diode I am not sure but I doubt it. Are there any 3D burners out yet? Would a 3D reader need to be this power? Some interesting questions here.
Both sides of the sled. The one I actually opened is on the left and didn't have the bar code sticker on the reverse.
Closer front shot...
... Rear shot...
Skinned. This sled has two seperate shrouds and I don't think you would need to remove either of them to get at the diode. It is a dead easy sled extraction! (You can see the little chip on the board there. It's thermally bonded to the indent, in the same orientation, on the shroud at the bottom of the picture.)
A closer look...
Rib cage opened up...
Bluray diode is bottom left...
Red diode in the non-5.6mm package is top right...
Both diodes, finally together. Ahh! The red is the one with the blueish AR coating. There is plenty of room to get a good grip on the heatsink from this BR. Clamp one side in a vice, and use a back and forth twisting motion with a set of pliers to weaken and slowly break the heatsink. These are not brittle but quite soft and work harden similar to lead so again, extraction from the heatsink is also easy for these.
It's interesting to note that the heatsinking compound in this sled was still either not properly set, or should be in this semi fluid state. Be cautious of this if you are extracting as this stuff will easily transfer to diode windows and optics if you're not careful. See the thumb print?!!! That's how soft it still is.
The BR diode has a curious green lining to the window. I've not seen it before but I may just have missed it... ?
Rear markings... They've even labelled the positive pin! (I think this is just an accident but it does look like it doesn't it)
The final reading! [EDIT: Again, ignore the peak value. This is due to tuning to 500mA. A little overshoot on current, (3-4mA), then paired back... ]
Some outputs for this diode are below. The rig used a LaserBee I at 150mm and a Jayrob 405-G-1 lens.

Pretty nice figures I think. I'm sure a graph will pop up shortly and I'll post that when available.
I can get hold of these too and would do a GB if anyone's interested as this gives us more options for 12x BRs. I know it's only one set of readings but I will post the other sled output as well at some point.
Thanks for reading...
