Eh. I sucked it up and grabbed it. I figure why not, since I already have a pure aluminum 9mm can and a spare G2 I won't push it very hard until it's been tested though.

Thanks Jordan for the sharing- and also TY to Dave, Andy and others adding to the info on these 9mm.

BTW


Just a FYI-

- 9mm blank modules and empty lens nuts are in stock a AixiZ and shipping is reasonable and very quick to CONUS-

shipping is also offered world-wide at AixiZ (Houson TX)

Blank glass lens mount 10 pack for AixiZ 12X30mm units, AixiZ


AixiZ 5 pack 15x50mm for 9mm diodes Housing Blanks, AixiZ

as well as copper blank modules(only the part where you press the die is copper) for both 5.6 & 3.8 diodes (made by Pontiacg5 in Kansas USA.)

They really were not. Most of them went to people that took the risk with me. I kept 5 to offer up on eBay to try to get something for my risk and time. I actually advised Wolfman not to buy them as I was asking a lot and he may just end up with a M140 quality diode just in a unique package but he decided he wanted one anyway. I currently have 2 left now plus the one that I have been testing.

Yeah - I figure why not? If anything, these will have better thermal properties because they have larger surface area to conduct to the Aixiz module. Who knows?

very interesting find/thread

great work as always, by LPF vets

My Diodes are Here.


Setting up for a Murder test Now. "Hope it doesn't die and just dims at MAX."

Iam going to plot everything like i did with the 638nm 500mW diode.


Lets see what one can do.

Now that is awesome. One day first class shipping.

All eyes on you, Angelos!

. This was Crazy fast shipping to me. You sure you dint drive past my house and just dropped it in there.?

wow my diodes are here too.
All 9 of them.
Thanks DTR!
Now ebay says my diode open is due today but still no here.

Oooo I can't wait to see some numbers!

Mine made it all the way to CA as well

I de-canned one.
It looks like I'll be sending it to tsteele for a macro
Here is my line drawing of the interior

The dark vertical lines are the posts
The center "shaded" line is the die/crystal
You can see there are still four "current"
wires

However, you can also see the ESD protection circuit
The fifth wire, in the middle, from the post to your right, bypasses the die
It is connected to an SM component
It "bridges" the anode and cathode

I'll be sending it out for macro shots



Peace,
dave

i wonder if the ESD protection is just a resistor/diode

My guess is, from the drawing, that it's a tiny spark gap for the high ESD to jump across instead of through the diode?

Might be a Lasorb or some MEMS based antistatic system.

My theory, its actually a very very small air plasma tube that "trips" at some set voltage so the static is dissipated in the discharge not the expensive diode.

At these scales, the gap might only be a few hundred nanometres so the breakdown voltage can be as low as 30V (!)
Its very ingenious if so.

-A

So wait we now have a a diode that has built in ESD protection? I wonder what other nifty surprises this thing has in it?

So now we get to tell bill to go screw himself with his lasorbs!

Did anyone use lasorbs? I always saw them and wondered if they were just a gimmick, or if they were legit. I never saw anyone using them in a build.

they are used alot more by people who build projectors.
They are commonly used in lpc arrays to help "save" the diode.
But it never works as they still die.
Most times once your build is put together the threat of esd killing your diode lowers alot.
Also the fact is you can build a better esd protection device even straight onto the diode pins.

Now all we need is a diode with a built in driver.

ESD Protection for diodes seams to be mainly needed for low power girly single mode diodes. These more modern higher power Mitsu and Nichas seam to be quite tough as nails, tougher than even gingers lazyorbs.

Alright Guys,

I have been going at it all day testing these.

I Test 3 different diodes to try to get a better idea of them.

Test was done on all 3 diodes one after another in the same Heatsink,module,G1 lens, Power supply & Ophir Laser Power Meter etc.

Here is the Simply heatsink and Ophir LPM sensor setup:


The DMM is the LPM Reading since my other display on my Ophir head only went up to 2A i used my DMM for the Display:



Each Mark was done in 50mA intervals waiting 1 minute in between each reading.

Here are the Numbers:

So it apears to have signes of Dimming ~2.2A-2.3A....


So those are the numbers from 3 of my diodes. I still have another 2 to test.

One Big thing i Noteced is was the Voltage is Much Higher for these. Like .5V More.

Our 5.6mm diodes are 4.2V-4.3V Maybe 4.4V "Rarely" at 1.8A.......

I do not like this Extra Voltage and this is a Big Down Side to these diodes.



Although there Not 3W diodes They appear to be very efficient diode. Especially the Last one. There Near 3W diodes.

They seem to be within the same power range of each other from 150mA to 700mA. After this is where you will start to see the difference between the 3 diodes.

Also IF your not aware of this 445nm diode very quit a bit with heat. Sometimes peak powers can range of a difference by 100mW or more sometimes.

In this Case, I re-tested all 3 diodes about 8 hours later and got this:

Diode 1) - 2620mW at 2.1A
Diode 2) - 2590mW at 2.1A
Diode 3) - 2760mW at 2.1A


So these new 9mm 445nm diodes are on Par with the 5.6mm version of the New M&H series diode. NO Question about that.



I will talk about the lens now.

They are Very Good lens. They are Equal or around the same as G1/G2 lenses power wise.

They Make a Killer Thin beam for Red 660nm and 405nm lasers."Single Mode Diodes" I love it. Its so tight its almost like the first 1 foot of a DPSS.LOL

For Multi mode diodes the lens is again on Pair with the G1/G2 lens.

I need to test them more to say anything else.



Here comes my Opinion.....

It comes down to Price.

Although you get a Very High Quality lens like the G1/G2 lens the diode appears to be in the same performance as what we get now.

The diodes I have all of them even the other 2 that i have not ran a Log of yet i tested them and They are all Very Efficient diodes.! The Higher One I have Now is Peaking Near 2.83W at 2.1A. This is one of the 2 i have not ran the Log Yet on and it was just a quick turn the currant up and then turn it down. SO it might even be more.

^That is by far the power-fullest diode i have owned or have seen for 445nm diode so far. Even though it was doing that at 2.1A its still more power then my other 2.8W Super Freak laser i built.

So Although i think these new 9mm diodes are basically the same as our 5.6mm 445nm diodes now i think they will all be for the most part very very efficient diodes.

Thoughts.?

Anyone that can put these in a Graph that would be Great.


Hope this Helps.......

@lazeerer

Which lens are you referring too, the stock lens that comes on the diode?

Looking at your figures there, I imagiine you could take ome of them over 3W if you keep it at 10c, just for a laugh and to be the only one who ever had a 3W 445 Diode.

Very nice! About the lenses, did you notice anything about the divergence you get with single mode diodes? Thin beams usually means bad divergence..
Maybe this means high-efficieny lenses will get cheaper than the G*'s are today..

Also, although these dims at >2A, they still might be the 1.6W nichia diodes, in which case they should be able to take the 2A without much stress at all. Maybe the manufacturers made them dim at a very point on purpose to pretty much make them invincible
