FS: >130mW PHR & 185-215mW 6x Blu-Rays, >300mW BR lasers in prototyping stage!
Franco: I am happy to report, that i revived the laser you got from Jake! (EDIT: for the unenlightened - it is about an inferior copy of Jayrob's design, NOT Jayrob's work!)
It was NOT the diode that gave up! It was the "craftsmanship"... (And i use that term looselly in this case. And i've seen worse!)
After i finally figured out how to break the seal of super-glue (superglue?!? :thinking without breaking appart everything else, i immediatelly spotted the problem. It was lack of any and all soldering skillz.
After i undid the problem, your lazor suddenly lit up! The diode was clearly alive and well, but...
There was this horrible disfigurement in the middle of the uncollimated output. Some crap got baked onto the diode window by the time i figured out what was going on. This is because it was shipped to me without any lens in it. (See, people, THIS is why i say NEVER REMOVE THE FREAKING LENS!!!! (And ALWAYS USE THE FREAKING LENS CAPS!!!!))
Unfortunatelly even submerging the diode completelly in analysis grade acetone, did not help a tiny bit to remove the baked-on crap. I have no idea what it was... :undecided:
I was about to give up, but i decided to give it one more try. I used a METAL tool to scrape the crap off of the diode window! I thought it couldn't possibly be worse than it already was, even if i broke the window. So i scraped away! And it took A LOT of scraping!!!! :wtf:
KIDS! DO NOT TRY THIS AT HOME! YOU WILL SCRATCH THE WINDOW, OR BREAK IT, OR RUIN THE DIODE SOME OTHER WAY!
The stunt was performed by a trained professional, and he almost shit his pants! :yabbem:
In fact, i am shocked, surprised and amazed, that i did not ruin it completelly myself!
Somehow the coating on the window decided to be harder than the steel tool i used, and to survive my scraping attempts unharmed!
The glue holding the window was luckily stronger than the pressure i used.
This is completelly unreal, and i'm still not sure that i'm not dreaming.
A few more acetone washes later, the window was almost as good as new, with barelly any particles remaining. Not completelly up to my standards, but compared to a non working lazor... Almost beautiful.....
....If it wasn't for all the other flaws.. But at least it works now. And at original power at that!
There are several modifications i would like to do before returning it to you tho:
- I have to cut the mini-heatsink shorter. It's too long, and puts the module in too deep into the lazor. Focusing barelly works for this reason.
- I have to remove all superglue remains, and replace it with thermal epoxy. That way there will actually be some heatsinking going on.
- I have to add polarity protection. Something that will destroy the battery instead of the lazor, if the battery was reversed by accident (batteries are cheap)... At the moment, there is no polarity protection whatsoever.
- I have to clean the window some more, so it's spotless. Maybe it's possible. I don't want to scrape anymore tho. :crackup:
After that i can ship it back to you. It'll be better than new when it's finally done.
But seriously... Superglue?!? :wtf:
