** ENDED **  PHASER diodes!

Re: ** FEELER **  PHASER diodes!

I also wanted to add something...the open can diodes we are harvesting from 20X DVD burners blow everything else away in terms of output. But so far nobody has been able to find specs on those. So yes, it is very possible Daedal has come across a gem, but I would like some more info.

Re: ** FEELER **  PHASER diodes!

i agree with Gazoo;

Daedal, if you can get a sample diode from the supplier, and put it through its paces i think people would be a bit more motivated for a buy once they see results from your tests and even some pics

Re: ** FEELER **  PHASER diodes!

Guys - the problem with requesting samples from the manufacturer is that they cost the same, if not more than teh actual product in most cases - especially when dealing with Laser Diodes. IF we all chipped in to a community pot for Daedal to order one of these beasties, I am sure he would have no trouble with ordering one to check out, and run through it's paces....JUST a thought - I would have no problems justifying to myself to chip in on a community project like this to see what this diode can do !
One little tidbit, though - kinda figure it as food for thought, really - I REALLY have a sneaking suspicion that this diode will be a multi-mode diode without fast axis correction, and will have a square beam profile - that is my prediction, and I would LOVE to be proven incorrect - and I will STILL chip in to find out ! Although, at the same time, I will be taking some side bets as to the diode's beam specs, etc.... Any takers ? :-?

So - if there are 10 interested parties, including Daedal - let's all chip in $5.00 and get this beastie ordered - if he sets up a google checkout account, he will lose no money to fees, and thus have the same amount of risk as any of us ! What do you all say ? I am IN !

Re: ** FEELER **  PHASER diodes!

ok sounds good to me SenKat.

i am in for $5.

now the only problem we MAY have is; will the supplier let Daedal order only 1 (and especially for evaluation purposes)!!?!?

if so rock on.

Daedal, i see you updated the front page with a interest guage chart.

add another one, for people whom are throwing down $5 to get you a sample. sofar senkat and i. come on folks! this could possibly be a killer deal.

Re: ** FEELER **  PHASER diodes!

This sounds very fair to me as well, but I would prefer to have the option to use paypal and add 50 cents. I don't think Daedal would mind. So yes, I am in.

Re: ** FEELER **  PHASER diodes!

Yer 5$ is nothing im in, dont want to fork out $50 to find it was a multi mode eeek.

I tend o agree with gazoo i don't doubt you for a second DDL its just the supplier

Re: ** FEELER **  PHASER diodes!

Yeah, if this were a $15 diode I'd get a few just to see. At $40-50 though, considering I'd want more than one if I bought, I don't want to be taking chances. If I can't get a general spec sheet and info about single/multi-mode characteristics, I don't think I can jump in on this one. Sorry!

If you could get them to send you a sample at ~regular price though, I'll pay the bill and you just send it to me when you're done testing

Re: ** FEELER **  PHASER diodes!

Put me down for 2 @ $50, or 3 @ $40. just finished with the lot of 80mw diodes i purchased off Ebay, need a bigger and stronger fix for my addiction now I assume shipping to the UK would be extra?

Re: ** FEELER **  PHASER diodes!

Guys, I am very sorry about the gap in my response times. I had a very busy day and I just got back home, I didn't even have lunch or eat anything since the morning! :-[

Well... As I had already said earlier, I sent an e-mail to the manufacturer regarding the original spec sheet of the diode and I am trying to find out who the manufacturer is. The problem with dealing with international sales is the time difference and the times when these people would reply is closer to midnight and past midnight. So it's kind of annoying to try and stick around for that every night. Although, rest assured that we have been talking this out and they know exactly what I am using this diode for. I have asked many times to get a diode for free to test it out. But simply put, if they were to send every interested person a free diode to play with... they'd be losing big time. It would be great for us though... :

Either way. I really like your idea for getting a diode to test out and report back. I even think that if I do get the diode in, I would have to raffle it off in an AixiZ module (and would put it in a nice flashlight for anyone interested) to one of the donaters. I couldn't bring myself to keeping it regardless. I have one problem though. The diode itself costs $50 for a single sample. The shipping will be around $30 (their estimate) and the fee to wire money is about $40, then there is a fee for currency exchange from the bank ($20). Thus, this one sample will end up costing $150! Hence why I said in my prior post that I can get 2 to test for $200. But $200 is not pocket change :-/

The other option is to send a money order. That should eliminate the wire transfer fee and the currency exchange (they can eat that, and I don't care). At this point the diode would still be around $80 to sample. This is assuming they like money orders in USD funds. They're free to get, so I personally don't mind doing that. Mailing it out will be much cheaper than wiring the money.

Once in, I will attempt to push the diode using passive cooling for 5 minutes constant at 200mW output and report back on the temperature output. Once that has been tested (and the beam spec checked), I will try to push the diode to 300-350mW with active cooling (TEC) and see how the beam changes. Of course I will test its burning ability (that is a function of the beam spec) and I will compare its visibility at night as compared to a 20, 30 and 100mW greens. The color will be compared to 633nm, 640nm, 650nm, 660nm to determine the actual lasing wavelength.

I hate to be so invaluable in this deal, but there really is nothing that I have not asked the manufacturer about. The conversation between us on e-mail was about 12 e-mails long. simply questions firing back and forth. What I got was a sample data sheet that was typed up, pending they acquire the original data sheet from the manufacturer. And until then, I can only go with what I have. I'll have to either find a way to duplicate the thing, or I can just post it as a picture on here.

Sorry guys, but this is all I got so far... Patience is what I was hoping for. I was not expecting this to go through before next month as I keep on their tail and make sure we're getting the best damn price they can offer!

Thank you for your support;

Re: ** FEELER **  PHASER diodes!

There is no rush....Lol. But wouldn't it be better to send it to pseudo, if he is willing to test it? Or some one whom is willing and has a power meter? Or maybe by the time you get the sample, we will have our meters... ;D That would be sweet.

Added: Oops , I see pseudo is willing to test it when you are finished with it...sorry.

Re: ** FEELER **  PHASER diodes!

However you want to do it is fine with me. If you want to test a single one out first and need a few bucks, let me know. I think once you get the official spec/ data sheet though, that should answer most, if not all, concerns.

FYIW, the diode sheet you did provide the link for- even though not the exact diode you're speaking of- starts at around $150+ a piece, so if this pans out the $50 for this more powerful diode would definitely be a steal!

Re: ** FEELER **  PHASER diodes!

Daedal - however you decide to make this work out - count me in as a participant. Since you have been doing all these emails, and fighting with time zones, you are getting a small taste of a TRUE group buy situation - the haggling involved, the agravation while waiting for emails, etc - you are being very patient with everyone's questions, etc...

So - start a list now - add me to it, and once you get the list populated with people willing to risk say, $10 - $15 of their money - if you get enough folks interested, get TWO samples - and when your testing is over, You can draw names, and divvy up the loot ! Your name WILL be included in the drawing, though - if you contribute, it is only fair, man - do not exclude yourself thinking it is noble - it's SILLY !

I am in

G !

Re: ** FEELER **  PHASER diodes!

UNfortunately I highly doubt they will accept a MO, and definitely not in USD, but if you could get a sample for $80 I'll buy it.

He could have easily capitalized the 'small' too! I appreciate what you're doing for us Daedal, but make sure you don't end up in over your head here. I think both me and Greg have had to spend out of pocket on GB complications and I'd rather you not have to join that boat.

Re: ** FEELER **  PHASER diodes!

Thank you all very much for the support.

I truly am trying my best to understand the situation and get as much information as possible. The problem with Chinese sales-people is that they are trained to respond back with a set of answers regarding every product specifically. SenKat and Pseudo, I am certain that both of you are very familiar with this situation. :'( All I am getting from my contact is a repetition of the same information but in different sentences! I am still haggling the price and still negotiating the sample. I was told that a money order mailed out and paid to their bank account would suffice as would a wire transfer.

In regards to acquiring the sample, I will get a final number for how much it would cost perhaps in the next few hours and will post it up here. That should include the shipping, bank costs, and the price of the diode itself. With that, and since the sales person is absolutely oblivious to the beam profile of this diode, I will be able to report back on the ability of this diode. The lucky winner will get a very nice laser diode, and possibly in a very nice housing ... my treat

Thanx all again for your continued support;
DDL

Re: ** FEELER **  PHASER diodes!

Whatever you need just let us know

Re: ** FEELER **  PHASER diodes!

Daedal - you are doing great...do not kill yourself trying to get answers if you gotta be at work tomorrow !
