There is a similar post to this one here recently but since my set up and problems are slightly different I thought a new post was appropriate.
I bought a completed laser from a forum member here a couple weeks ago. On inspection it appears to have the same driver Rick Trent is selling on eBay, one of the four mode with three output levels and strobe. The laser was pulling 3.2W when I received it and a couple days ago I pulled it out from my case and started playing with it, immediately I noticed the output was about half of the previous output. All four modes work but each is now probably half the previous output. I have not LPM'd it yet but in comparison visually to a known 1.6w blue, the max output appears very close.
For the record, since I've had it I have less than 30mins total time in operation. I have no idea what time the diode had on it prior to my purchase. I never dropped it or changed anything (batteries, etc) between the time it worked well until now. I don't think these drivers are adjustable either.
I have had diodes burn up to where the output drops to about 5% of original then completely blow a little while later. I've never seen one drop to half the output before.
I plan to try the diode with a different driver soon (one on order) but my intuition tells me this is the diode. Looking at the internal views on DTR's website it appears the diode element receives it's current through about five or six hair thin wires. If one or more of those wires fried could it lead to a reduced output like this? Anyone here have any similar experience or insight into this?
It would make some sense that you could get reduced output if one or more of those hair thin wires burned up and it would also make sense that if they did, the remaining current would try to route through the remaining wires, thus burning them up in short order a little while later. Does anyone agree with this theory?
Please let me know y'alls experience with these. They are new to me as I've been away from the hobby for around a year now. I am really excited about these new diodes but am starting to get suspicious they are being driven too hard by some (me) and it would be nice to know if that is correct.
Thanks!
