GB: PL520 murder fund






Do not use an X-Boost with more than 4.2V! Direct word from Angelos, these weren't meant for that type of voltage. I'm running my 520 fine with an X-Boost and a single 18650. These are boost drivers, they were MADE for LOW voltage builds.

I made a mA/mW chart from the data.

Thanks Blord! :) The diode is now up to HALF AN AMP and still lasing :eek: I thought it was about to die soon after 400mA.

By the way guys, you can open a chat on the wide of the spread sheet. Click on the "Other viewers" in the top right.
 
It stopped outputting light at 760mA. I drove it up to 1A after that and it didn't die, still outputs the same when I turn the current back down. This is the most resilient diode I have ever come across.

From the data of the first diode I would say a cap of 350mA for these diodes.

I think to kill it I will have to see what kind of wavelengths it makes at 100°C ;)

This seems to be a common theme with newer diodes that are coming out. We have seen it in diodes like the 445's, 638's and that new 405 that Lazeerer got a few samples of which was also a 3.8mm diode.
 
I'm glad they are this resilient now. My first few laser diode experiences were not happy ones :p

I hope nobody minds if I go in 10-25mA steps for the second diode, this first one took all afternoon to catalog. I was expecting these to die at around 400mA so I thought 10mA steps would be ideal. :rolleyes:

I'll make the graphs after the data from both diodes is obtained.
 
I did drive mine up to 500mA and it is still kicking perfectly though the output saw no benefit at over ~350mA. I am now set on driving mine a little harder than I was first going to. I did however notice a barely visible wavelength difference as I cranked mine up past 400mA.
 
I am thinking about driving mine at 300mA, does this sound reasonable for decent lifetime?
 
I don't think any of us have enough research on them to even know the direct effects of high current on the lifetime. They seem resilient but until we have a lot more runtimes on them I don't see it being possible to make a very good guess. Based on our driving of other diodes we typically get away with double currents and the diodes appear to survive quite well.
 
Oh well...I still have to figure out driver setup. I have a C6 Host coming my way from Mohgasm....I may just wire it up in there for the time being. I could use a Linear Driver with 2 Cells for an easy build that I could take apart once I get my Host and Driver for the MS-V4 build....
 
Seems to be asymptotic at around 130mW... So since they're that resilient, might as well target to run them at 130mW?
 
From my exp its generally best to run below the maximum output point. For my builds, I usually target somewhere in the middle of between the point of greatest efficiency and greatest output.
