Hey Andy, how come I am only down for 2 instead of 4 if this has been updated ? :confused:

Andy may I respectfully suggest that you arrange a Google Checkout like drlava. :D

Their system appears to work! (without them needing your grandmother's maiden name).:cool:

Did you send the PM as per the request as I cannot find it, I cannot find it?

This PM thing was done to so we can keep the GB in order, who asked for the diodes first will receive them first.

Andy -- You really have to be over 200 now. When will you order?
:confused: Tell them we want the HOT ones

And the price was for 100+ ;) Lasercingi could get the diodes ordering with a quantity of 50 for 180 dollar. Very smart to wait until you have 200 :rolleyes:

We're stuck at 195 diodes for days. Is there no one else interested?
Looking at the data sheet, I suspect higher current and PO like the 445.
I'm in for one hoping the $$ drops like the 445 diodes.

I'm sure there's intrest, I would have intrest in 2 more.. but still questions remain,
What will the end price be, cost of optics, near and far field beam specs, net power after optics?

i think he want a bit more detail than that
i dont think i will bother , i cant se him getting the divergence of these
diodes any where near what the 445's are, as you know your self
but we could be proved wrong,
if hes that busy send the kit to one of us we will have results in days

wow that bad eh? if thats the case I might have to skip on these... someday we will get red that does not suck O_o

I too would like to get the diodes in hand....that way we can see what is usable to each experiment. It would be nice to go ahead and place the order...and send them out so we can tinker a bit with them. I figure they are better than the 635's I used to fool with....but may go back to 635nm if these do not emerge soon.........prisms and keplerian tele.....here we go again But then again there is hydrothermally grown crystals that are capable of mega red at 658nm pumped with 442nm......Hmmmmmmm.........low % chromium with silicate of beryllium and aluminum grown in a platinum lined chamber.

Very low fat content, recommended for slimmers. *DZ

Well WTF man... we can BS 442 with 445 adn there seems to be a lot of that lying around. *vigil

Any update on the red diode GB? Its been at 195 for a looong time.

Hi Mike,

Yes I know,

Have all the lenses here to finalize the testing but more important stuff keeps cropping up, am busy like a dog chasing it's tail lately.

I'll take 2, if I'm not too late to the party.

I'm just interested in the diode only. You still seem stuck at 195 diodes.
Is the diode GB still going?

ME3 -

I agree --- I have a grin I would like to try plus other lenses. If I can get what I see with my 445's, I'd be happy but we need the diode to make the preliminary tests.

sent a OM last night that I would take 4, so that would put us over the 200 I think with the other two pair added recently. Let make this happen. $150 each now ?????

It appears that Andy is overwhelmed by this GB. Is there someone here with experience who can take over this GB by working with Andy? He hasn't replied in a week and ME3 and I are ready to test diodes!

HMike

I don't think he expected the responce he got and has retreated to the womb. This GB will require a fair amount of cash and WOW -- He's gone !!! Forget the lenses ... Just the diodes are too much.

Can we just get ahold of the rep for mits and have everyone order direct? The rep can consider it all one order and give us the cost break but have them mailed out individually or maybe to two locations, one in the us and one in europe. I wonder if we wait that they wil show up in a new casio projector that's all lasers?

Wow ! that would be a really FRIENDLY rep. :cool: or when you say "get ahold of the rep" maybe you were thinking of a somewhat more forceful approach ? >:)

As HMike points out, it involves a load of boodle requiring a careful eye, and maybe Andy IS just TOO busy ! :(

well if you think about it this is a 40k order!
09-12-2010, 08:11
andyf97

HAHAHA,

You guys are nuts,

We have now 208 diodes to order will be updating the list later, the GB is not more than I expected as I know we will order even more once a few get the hands on the diodes.

I will be asking for an update price tomorrow based on us reaching 200+ diodes.

To source the diodes from another route likely the cost will be higher as we are talking here of very spacial rates from not only a simple rep but a long term friend.

Let me explain this situation again for those who are relatively new on this GB:
We created this list to document who would be interested in the diodes once we have established the correct lens setup. I have done some initial tests with some bog standard lenses and have very good results.

I waited ages to get a set of good quality lenses to finalize the test so we can have two lens options for two styles of combining and it is this final step that is taking time as one of the lenses is tiny and I am struggling with time to create a little mount for it..

We can go ahead and buy the lenses, you can all pay your money but then you will be going crazy asking me ANDY what lens combination do we need. So being fair to you guys I say wait until we have this info correct so we can do also a GB that we can add the two lens options for the diodes, then you don't waist money or start going crazy once you receive the diodes.

Waiting for 200+ to save you guys money, no other reason. So if you want them faster we can order a batch at a lower quantity but of course the price will be higher.

If we are patient and establish the right lens set, everyone will be happy and we will order 200+ diodes at a very good price.

Simply my time is spent on large projects and as I don't add to the price of these diodes it becomes more of a favor I am doing you all.

By the way, am not even in my city for the past 10, now I am in a hotel and will travel tomorrow to be there fr one day then leave again for a few days.

Anyone out there wants fabricate a small mount for the lens, it will help a lot. I can also post a sketch for it.

It will need to be almost the same as say a typical axiz style lens holder body but with the ability to place a tiny lens at one end of the mount that is overall ~3mm OD

Looking at this from a calm detached perspective all I can say is this:

Hey ANDY, I'm going crazy.......what lens combination do we need ? ;) LOL

Yes this is true...at least of me. Why else would we be involved in this hobby ? Lasers have won out a lot of other things in life...some not to be spoken of.........all the late nights and endless searches for "that" lens combination source......
09-12-2010, 16:02
Hemlock Mike

ME3 --
I'm sure a lens kit will add to the beam quality. In the meantime, a sloppy Aixiz lens with a DIODE would start the data flow for this diode's curves.
Does it have a knee, does it fold back ??? We don't need a great lens assembly to start the science.

I have checked with Mitsu for a new price and annoying there is no major gain for 100 to 200 units so the price will be the same. It solves one issue tho that if people drop out of the GB then likely we will still be over 100 units.

There is a small margin that will cover the shipping based on flat rate packet service with tracking so we will make the price as above and include the shipping to make life easier for everyone. If anyone wants to have a special service like DHL,UPS,TNT,Fedex I wil get a cost. I have also updated the first page to reflect this.

There are some skeptics here on the ability of the diode based on it being 40um stripe but 40um is not a problem, I find it to be ok and will prove this to be a very good diode.

If any of you want to go ahead now and get the order done so you can play with the diode sooner, we can do this for 100 diodes without loosing the price break or you can all wait till I get the evidence together to show you how to correct the beam.

So if any of you want to move faster, just drop me a PM and I will send you a paypal address to send the payment.

Waiting for feedback, comments etc..

Any guess at what the cost of correction will be and will it be able to be purchased later if the diode was bought early? Thanks
