Re: FS-IGORT build bluray 191mW
Can we have a bit more info please? What model diode? What current is it set to?
It's a GGW diode from my old stock (the original 79), which means
a REAL GGW diode - without kinks, and not the fake crap the Chinese have been peddling for months now, which are in reality prototype GGW sleds with old GBW diodes inside - with kinks all over the place (i lost over $1k on ~20 of them before i started testing them and figured it out and i can't get rid of them, cos i can't honestly sell them as GGWs when i know for a fact they are not)!
I don't know if "GGW diodes" are still being sold, but if they are, they are really 4x's not 6x's so the diode in here is superior to them in all respects (even tho it's slightly used). Real GGW diodes don't have kinks (ever).
It's also a good efficiency GGW ("cherry-picked" for Murrat), and if memory serves me right it doesn't seem to have degraded much since it's been made - it should still have at least 90% of it's original life expectancy in it, if not a bit more (i'll need to check my data and dig up it's PIV plot), but i think it started out at 193mW. If it is now at 191mW it would have lost 2mW and it's quite possible if not likelly that some of this is from the lens degrading or getting dirty (real indication of degradation would be a power comparison with a fresh lens).
Murrat originally asked me to set it to just above 190mW for a longer life-span (it was a conservative setting for this diode), but it would work just as nicely above 200mW (altho i wouldn't recommend anyone but me trying to change the current, since it's running on my driver set with fixed resistors)...
Otherwise i found Murrat to be more than trustworthy in my dealings with him, he traded me an Aquarius (my first blue laser) for it and sent it up front...
If you use PP for the transaction and he ships registered and provides a tracking number i don't see a problem.
If the end buyer should want for a different power, i would gladly "refurbish" it (for free obviously) if it helps Murrat sell it. I'll also dig up the diode's PIV Plot to check how much life it still has in it exactly and what current it was set to (but i know it's under 200mA).
