Seeing as he hasn't responded yet, i'd charge back.

He wrote back and said I could send it back and he'd replace it. I actually found the auction first and then googled for the sharp diode and found this thread, so I registered to ask him about cooling and duty cycle and stuff. If I'd have seen the thread first I agree I probably wouldn't have ordered it, but whatever. I don't get the feeling that he's trying to scam me. Hope I'm right.

“It's not a 6x diode I do not mod my lasers the diode I use in this pointer I done now is a 150mw doide i am running it at 120mw but does peak at 133mw then goes down and stays at 120 to 124mw it runs at 210ma. The 200mw diode i got runs at 420ma so got to use a high power driver .
The 6x diode you talk about should only do 65 to 70mw after that to get more power you over drive it so its a mod and makes the life short on the diode.
a 6x laser pointer is not in the same class as my laser pointer because one its not modded and two its a diode that does that power and was made to do it .
you can get high power blu-ray diodes if you know where to get them from and when you know people who work for big companys it makes my job easy.
you might think a 6x blu-ray is the thing now in the shops to get but next years blu-ray is already on the work bench which is 8x or 10x and is already been made they are not going to sale it now because they want to sale as many 6x blu-ray before bringing out the next model.
in the high tech world of video,tv and hifi what you buy today is out of date by tomorrow .”
Who is this guy trying to kid? A 6x pulling 60mW? I’ve been running my 6x @ 200mW for weeks now, and play with it every day. His feedback on eBay has nothing to do with lasers. I only see low priced junk (as a seller), and the rest was too long ago to view item. Another thing he mentions is the peak, and the subsequent drop. In every BR build I have done, weather it be driven with Dr. Lavas drive, a 7805, or LM317, one thing has been consistent and that is from a cold start, the power only increases. If you power it from an AC/DC source and even fresh batteries, they seem to output more light as they warm up.
Im sorry to hear that things went this way for the purchase you made, and hope that he will own up. I have had only a couple of returns with my sales, but always make things right. If an assembled unit is sold, then the issues with the unit reside on his shoulders. If it were a DIY kit, or parts there is always the chance of the buyers fault, but that isn’t the case here. To cover your butt, I would file a dispute, and hold off on the chargeback giving him a fair chance to resolve this. With the money involved don’t take any chances and end the dispute until a new laser or money is in your hands.
Best of luck,
Joe

My thoughts exactly. And to say that our diodes are "modded" makes no sense. We're doing nothing different than him and as it turns out, ours are surviving at 200mW much longer than his at 150mW ;D
Oh, and wannaburn, what current are you running now? I'm still at 170mA (peaks at about 180-190mW after the lens) but I'm thinking about going up a few more notches

Ive been at 210ma for the past week and a half or so. Ive have been judging the output with heat and kinda going from there. Remember the heatsink im using is a bit big approx 20mm dia., so mileage will vary. The key ive noticed so far is keeping it cool and happy

My heatsink (head of the kenom barrel) is about the same, right around 20mm. Do you find that yours doesn't like to be cold? My window in my room was open all last night, and I just took it out to measure power for fun. The metal was very cold feeling. I fired it up, and it climbed to only about 140mW. After about one minute run time, it had finally climed to around 185mW. When its already warm it doesn't really have this issue. Kinda weird!

It almost behaves like a greenie in that sense, must be the nature of the beast. Ive noticed that with all the BR's I made through the winter, where as any red ive done love the cold. The optimum temp seems to be around 30c, you just have to be careful with the thermal creeping effect. Ive blown a 803t which was running nice, and was watching the temp. Out of the blue, the temp jumped a few deg's and p00f!

Man, the fact, that he is going to replace a <$30 HD-DVD diode in your $700 laser does not mean he didn't scam you. He was lying about this laser using a top secret super powerful diode, that should be capable of much more. If it was really better than a 6x BR diode, it would have to withstand 300mW and not die at 120mw.
For $700, he should have made you a laser with a 6x Blue Ray writer diode, that would not die at that power level or even at a higher one. Some people are getting 200mW out of 6x diodes.
The only reason he succeeded in fooling people even here was, because at that time, no one knew it was possible to push the HD-DVD diode that far at all.
Now we know that diode can do 150mW and more if overdriven. But mpmitch wasted a lot of that in the wrong lens, that blocks 405nm light.
He didn't even put any thought into it. He just quickly threw some parts together, and made $600.

Exactly.. The expressions he was using were borderline retarded.
I guess adjusting the current is a "pot mod" for him..
I doubt he even knows anything about lasers.. He was just full of big words that don't mean much, but might sound impressive to someone new..

Oh so this is what people do all day on here is slag me of ? well thanks alot.
lets get a few things right here i am not ripping him of or trying to take him for a ride ok.
I am abit upset that this as gone wrong i made over 20 of these with no problems and one of them go wrong why ?
Well i will not know until i get it back to see i am not happy at all its gone wrong .
The other thing is that it does use a sharp laser diode that is rated at 250mw and if you lot want the diode number its a GH04P25A2G
made by sharp ok . The reason i was not telling because a friend in sharp got them for me but now it don't matter because he say it's ok to post it .
The one i sold him had the right lens on it for 405nm and not one for 650nm .
I did sell it to him as a 150mw laser pointer but it was doing 180mw in the end and i done good tests on it and it past but for some reason it as gone wrong and i want to find out why.
It might be a faulty diode or could be a driver problem but will find out when i get it back .
So tell me everyone here i had a laser gone wrong out of loads of lasers i have made does that make me a bad person here ? i am not a con man and i am not out to con people i will help to put this right for him.
i spoke to him on email and he is sending it back and i will look at it and put it right for him and i said to him let me know what it cost to send it back so i can give him the money for post .
so if companys make lots of items and one go's wrong that means they are a con ?.
At the end of the day i will help to put this matter right for him so please no slagging of.

LOL, I thought it wasnt a 6x?????

I do hope that the buyer makes a photo of the bottom of the diode first, and posts it here.. That would prove you are telling the truth, right?
By now we all know a PHR diode can do 150mW. Especially after the right optics. What kind of lens did you use mpmitch? You said it was glass.. Was it a triple element glass lens - the one, that reduces distortions in the beam? Or was it an aspheric lens?
And i remember you posting in the PHR803T thread that you just got them, shortly before you started all this. So many coincidences. And so many big words..
