Re: 6x Blu-ray SLEDS GB! THEY ARE GOING FAST!
I just did a more careful comparison, and i think this 4x is the best Sharp GH04P21A2GE candidate so far! The Sharp diode is rated for 105mW CW and 210mW pulsed.
The GGW 6x never really matched it, because it has a much lower Vf. The PHR is a much lower power diode, to be rated for 105mW CW and 210mW pulsed. But this one could be it!
I used Rkcstrs P/I/V plot, to compare the Vf to the plot in the Sharp datasheet, and the Vf matches really well.
The power is harder to compare to, because the datasheet shows the raw diode output (no lens), and we don't really know how much is getting lost in various lenses. I had to guesstimate a little, and i multiplied the powers in Rkcstr's plot by 1.28. And surprisingly enough, it matched (and i didn't do it backwards). Of course this is the part, where imagination can play tricks, because the exact losses are unknown, and to make it worse, each graph will only match one diode.
Another thing worth mentioning is the lower wavelength drift as the power increases, compared to the PHR. Drew mentioned the 4x remained violet, while PHRs turn "white" or rather blue-er as the power increases. The Sharp datasheet specifies a 2nm wavelength shift from 10 to 105mW, and would seem to suggest a better wavelength consistency, except for an occasional "wavelength-freak".
If this is the same diode, it reaches 210mW at 190mA on my guesstimated raw-output plot. If so, 180-200mA could be a "safe" current for it, since most diodes can survive being pushed to their pulsed power ratings for a decent amount of time. Of course, that would mean 165mW after AixiZ, but it should survive it for much longer, than a PHR.
The Sharp datasheet specifies the max CW current as 120-150mA, depending on threshold and diode temperature, or rather, whatever is required to make it put out 105mW (it is their own output power, that kills them, so a hot diode can survive a higher current, than a cold one, as the power will be lower).
Not that this last part means much to us. If we used diodes within their ratings, the PHR blu rays would have 40-60mW and the open cans would be <200mW.
But it would be nice to finally have a blu diode with a datasheet.
If this should really be it's datasheet, it would mean, that the GGW 6x is a higher power diode, than 105mW. Could be around 120mW CW/240mW pulsed, and would explain why my GGW 6x is still alive putting out >250mW (raw output).
Of course for now, i am basing all this on the data posted by others. I will definitelly do a more careful comparison when i get mine.
But for now, i'm attaching the datasheet for those of you, who already have the diode, but haven't seen this datasheet yet... I really think this could be it, but maybe i just want a diode with a datasheet too much.. ;D
EDIT: Replaced the renamed .RAR file with a proper .ZIP file. It should work now in both WinRAR and WinZIP without renaming the extension.
