Jay: You are correct in requesting that, because it does make people think of your work...

Not to mention the mixup with the hosts...

I should have made it more clear that it was an inferior rip-off of your design. Did so now, left any names out tho....


I am sorry for the confusion and the mess.

More than a little shocked, i fell into explaining what i found upon opening it up, but didn't take enough time to check if my words could be misunderstood as to WHAT i was repairing...


After rereading them, i DID find a way to misunderstand them, so i changed the sentences completelly.

I hope all is well now...





Otherwise, Jay, what do you think of my diode window scraping attempt?
I am still in complete shock, that not a single scratch is visible!!!


I can't believe how hard these coatings are!

I modified the tool (and i won't say what it was so as not to give anyone funny ideas - if someone NEEDS to know, email me) before the scraping, by first sanding it round and then polishing it with several different finer and finer polishing tools, to minimise the resulting scratches (which i was 100% sure would appear). But they didn't!

I mean, i did it out of utter desperation. I thought that it can't get worse than it already is, even if i break the window! SOMETHING got baked onto the window - in it's direct center where the light intensity is the highest - in the few seconds of my first power-up attempt!

It got baked there so hard, that acetone could not dissolve it even when i filled the module to the top with it! Nor could other polar or non-polar solvents (and i have several, which i went through before resorting to STEEL ).

I still can't believe it was STEEL that finally did the trick!



Interestingly, the acetone started leaking out from under the diode way too fast, when i filled the module up, making me think it is not even inserted properly.

I'm thinking if i should use the removal tool you were kind enough to make for me (THANK YOU VERY MUCH, Jay!) to take it out, before cutting the poor copy of your sleeve (mini heatsink) shorter for a better fit....

That would also allow me to apply some thermal paste between the diode and the module before reinserting it. Something that is even more important in smaller lasers.. Altho i think i haven't made a single laser, be it "big" or tiny, where i didn't put thermal paste between the diode and the module yet.


I think i should take it appart completelly, so that i can also check the actual current setting, and even plot the diode (never seen a SF-AW before).



But that's all for later.

It's evening now, and i have three special diodes to plot... Too bad i can only do destructive testing on two of them..

I'll double check the emails to make sure i didn't miss anything else.

Jay:
I regret for the unpleasant "identification" terminology mistake. I have cleaned the wrong wording from all my answers. I think that now it is clear to everybody that the laser I sent to Igor has been manufactured by Jake21, and that the quality of your products is NOT under discussion at all.

Hey you guys, thanks for fixing that!

I know it was just an accidental use of the host name, but really cool of you guys to fix that.

Hey Igor, I can't believe you scraped something off a diode window with steel and didn't scratch it! Man! Well, if anyone could do that tedious of a chore, I guess it would be you...

Glad you like the tool I sent you! It's stainless steel, so hopefully it will last and not get bent up. (thin wall)

Jay, it was correct of you to point out the potential misunderstanding of WHAT was being fixed, and mistake in the hosts name.
I wrote too fast, trying to be funny in the process with what i called it, and didn't even consider the possibility it could be misunderstood.

I'm glad you spotted it, and had us fix it, so that no one can misunderstand it now - that i am calling YOUR work crappy or anything like that - something which i would NEVER do.

I love your work, as you know yourself, i use your services for prototyping, and i would NEVER send my expensive lenses for mounting to someone i didn't trust 100%!


I hope that is clear. I always recommend your work to anyone who asks for kits.

Actually i must have been VERY LUCKY! Cos i did NOT expect such results. I thought i'd scratch it all up in the process, but that that would be better in the end, than having a big blob of crap in the middle of the diode window.

At least i could plot the diode afterwards, that's what i was thinking, never in a million years would i expect the diode to be as good as new afterwards!

I guess i'll have to try this out on some cheap PHRs, to see if it can be repeated or if it was just dumb luck, before revealing how i did it.

Altho i hope it's never necessary again! I mean, i have dislodged windows from rare super-freak GGWs, just by cleaning them with a soft q-tip and a solvent

I know it's a thin wall, but i use it carefully and so far it is still exactly the way it was when i got it.

I don't know how i lived this long without it! Do you have a thread somewhere about it? I need to post a review, methinks..

I don't have a thread on it, because I have not offered it...

I just made it for you because you asked if I could. Personally, I rarely use mine. It's only for removing a good diode without damaging it. And most of the time I remove a diode from a module, is because it is dead. So in that case, I just punch it out with a flat tipped punch...

Yes, i also simply hammer out the dead ones.

But there is this one case, where the dead ones are supposed to be returned in tact, if you know what i'm talking about...


Then there was this 100mW Nichia diode i was very impressed by, but i put it into an AixiZ module... Well, i would like to have it somewhere else..


Then there are all the occasional upgrades i do. There such a removal tool can come in VERY handy!


So it's already helping me a lot, and i'm sure it will help me even more in the future...


Thanks again!


P.S. Diodes installed and hooked up...
Torture begins now. Sleeping postponed.... For a day or two.

Pre-Torture complete!

Compiling the data now....

After that, two of the diodes go into the Diode Torture Chamber, to be cycled to death.... The third goes to Franco, to live happily ever after.


This time i'll also try to make Pe/Po plots for a different type of diode comparison (if i can figure out how to do equasions in Excell... )

I couldn't figure out at first why i can't see it myself. But the answer is 405nm glare...


It's the splash! That's what the splash looks like under certain focus conditions. It makes a small separate "dot" (altho disfigured) under specific focus settings...

I use my beautifuly fluorescing mini-fridge, mostly for spotting particles on the lenses or diode windows, by enlarging the spot, but i just noticed that the splatter becomes a funnily shaped "dot" under certain focus settings while playing with my personal super-freak 6x....


Now that i know what i'm looking for, it will be easier to take pictures of...

Default Re: FS: >130mW PHR, >185-250mW 6x Blu-Rays - 300-400mW BRs on request!

Ok....

My hands were trembling, when i started handling this diode.. I had to calm myself down first, before i was able to start soldering to it. And then, for the first time ever after making almost 150 BluRay lasers, i had to check the pinout diagram again, just in case!

I quadruple checked for every smallest danger, before moving on to the next step. I was never so worried about a diode before in my entire life!




BEHOLD:
- The BDR-203BK 8x diode in FrancoG's lazor! Well, rather it's P/I/V plot...
- And my Pre-Testing apparatus (Diode Analyzer) during plotting, when i decided enough is enough, and took a photo...



P.S. Franco, you are one lucky..... I think you got a high efficiency 8x diode by pure chance!
I mean, i calculated, that this diode would only need 355mA to reach 500mW through Jayrob's lens!
Not that i think that would be healthy... I think we should leave it at 290mA.. What do you think?




P.P.S. My hands were trembling again when i was taking the photo, as is evident from it's blurry state...
I have not been this worried even when handling my first GGW, which cost me $100 more! But that was my diode.. This wasn't....

Now the dangerous parts of the work are over, and it just needs some minor finishing steps before shipping...



Check out the thumbnails:

- On the right, my Diode Analyzer at the top of the plot, showing 414mW on the meter at only 290mA!

I quadruple checked for every smallest danger, before making the next step. I was never before so scared of a diode in my entire life!

What I think? I think that I'm happy! The first 8x BR "IgorT made"!!!

Other members are not aware, but before this successful conclusion, so many messages have flown the Internet, between Igor and me, that it was quite the contacts with the ISS.....

290mA are more than ok for me (I prefer a longer life at a lower P.O. rather than the contrary)! And having followed all the tests you have performed during this afternoon, for the setting procedure, I'm sure it will have a long life! Thank you Igor , and thank also to Glenn who supported you shipping the 8x sled...

You're gonna love it!

But you better put the glass lens in the moment you get it, cos the plastic one is going to melt.


Otherwise, when i started the test at 0mA, the temperature of the diode was 26C.
When i was done with the high resolution test at 290mA, no actually after taking several photos of the setup, the temperature of the diode was 30C...

The test took quite a while to do in this detail, but the diode remained cool till the very end, even tho i put it directly into a v3 Heatsink/Module and into a host, instead of my usual pre-testing setup, where i use a HUGE heatsink from Tallaxo....

I think the v3's are doing a damn good job!


But during normal use, you will measure even more than 414mW, since the laser will start out cold...




Otherwise, do you need the raw PIV data for your compilation?

A very nice diode indeed! 414mW's at 290mA's (405-G-1) is sweet! And I noticed that the forward voltage is low too! Compared to Dave's diode, which is up around 6 volts at that current...
