SenKat sent me a couple new laser diodes to test. These are 5.6 mm 808nM pump diodes we recognize from the days of modding pointers. I have purchased a couple of these from Tony on ebay for $38 plus $$$hipping
These diodes are standard size but have no window and SenKat says they are rated at 200 mW. I mounted the first one in an Aixiz style module for testing through a plastic lens assembly. Testing is made here with no TEC cooling, regulated power supply and a Scientech 365 power meter. Current increments are made at 20 mA intervals and the diode gave me about 15 mW per 20 mA step right to the top.
I stopped my testing at 0.500 AMPS !!!! Reading 374 mW !!!!
Now the bad news ---- As you all recall from the modding days, go over 300 mA and you're risking your diode. I ran this diode later at 400 mA (270 mW) for a life test. It was fun burning stuff for about 25 minutes
The second diode has been run for over 4 hours at 200 mW (320 mA) showing no degredation in power out.
This is a good little diode for those of you wanting to experiment with IR or give life to that poor old greenie you toasted StoneTek tells me he has a limited qualtity of these and for a price far less than ebay.
