So, it's been about 3 years since I was quite active on this forum, and I decided to come back since now I have slightly more experience with electronics than I did previously. I have been spending the last few days trying to see what's with the "new" (to me) 445nm diode lasers, and while I see everyone using ordered drivers or simple linear drivers, driving them to 2A and beyond for 3W and beyond, I can't seem to find any thread or post detailing what the 445nm diodes are typically like.
I remember there were threads talking about properties of red (650nm) and violet (405nm) diodes, e.g. they need 3.2v (iirc) to lase, and the PHRs needing 5v (?) or something, since most were trying their own DDL drivers or other more elaborate self-built drivers.
So what about these new M140s? What's the voltage needed to lase? And has anyone tried a DDL driver for it? What's the min voltage needed to run that?
Also, from back then, typical max current for running reds were ~320mA for 250mW (I think this was Jayrob's MXDL build), but that was pretty risky, with most people settling for ~250mA for just under 200mW of power. These were standard AixiZ acrylic lens (or for those who paid the premium Meredith Glass), and so I could tell what were typical current drive values. But now with a number of lens options available, I'm seeing a huge spread of powers, from 1.5W to 3W outputs.
So what is the typical drive current for the M140 for long life? And what's the max power that anyone has gotten so far?
I would like to get a feel for these new diodes, and I hope anyone's experience might be useful!
