Yes. You should also notice that the entire bar code itself is smaller than the bar codes on the other didoes we've used.

Goregeous shot of that diode. I'm glad at least some people know how to take photos.

I know how to take photos... Just not super closeup macros like that one... [smiley=embarassed.gif]Bionic-Badger said:

Just seeing a picture of that differnt marking makes me want to buy one!
How much estimated time do you think you have on yours now Dave?

It is definitely a different diode
I have 40 minutes on it now.

quantile said:Tried to power up the drive (without its violet LD), green LED comes on, it registers fine in Windows as BDR-203, but it did not do anything when a disc was inserted. You want your diode back? Alright, I'll give you one, just not the 8x
I put a PHR in the original heatsink, glued it back to its approximate position on the sled, and soldered the little ribbon cable back on. Power up....
... it's alive! Reads CDs, DVDs, and I just burned a DVD-R at full speed without problems! Probably it just needed something with a ~5V voltage drop on its violet LD pins.
Here is a close-up of the 8x diode:
awesome! i bet thats a first-time hack of an optical drive, it surely didnt see *that* coming! talk about a frankendrive.. ;-)
impressive close-up of the diode too! there are people here who would love to have such high-quality pics of common diodes.. if you have/get more diodes, do a comparison thread perhaps?
actually, with such pics.. do it to any diode you find! someone decoded the 2d-barcode with a mobilephone, with more of those, we could perhaps find new patterns and distinctions?
ah, just tell us how you did it, already!

That truly is an impressive shot of that diode. You must share your secrets!
Thanks for your comments, glad you liked the photo.
Above shot was taken using a Canon EOS and a macro lens somewhere near 1:1 magnification - not quite into microscope territory yet.
It's not all that difficult: Use a tripod, diffuse light (no on-camera flash), close the aperture as much as possible (field-of-depth is very thin when shooting macro) and expose as long as neccessary (the shot above was exposed 5 or 6 seconds I think), the diode will not run away
As always, decent equipment helps a lot, but you can get pretty good results with smaller cameras too, usually they have pretty good close-focus capability. This was taken with a four years old point-and-shoot (PHR diode):
Here is a group shot of my violet collection, from left to right: Nichia 120mW from o-like, 8x (BDR-203), PHR-803T.

Very nice pictures! I like your 8X burner resurrection.

I am staggered by the quality you got there, so +1 to you!
I put the 8x in an Aixiz module and took some measurements (after Aixiz acryllic lens, back not opened up):
Lasing threshold is ~35mA
I/mA Po/mW Vf/V
40 9 3.98
50 20
60 31
70 45
80 56
90 70
100 82 4.62
110 95
120 107
130 121
140 134
150 151 4.98
160 165
170 178
180 194
190 208
200 221 5.60
210 232
220 247
230 262
240 275
250 286 5.85
260 301
270 317 5.92
At 270mA I hit the limit of my LM317T circuit, I'll have to find a smaller series resistor. Don't think I will get to that today though...

Some good data and photos coming through here!
Looking forward to the lifetime tests as well. Good work on investigating the diode, if we could get the datasheet for the SLD3235VF and SLD3236VF it could be used to confirm which diode this 8x uses.
