A140 current

[moh17]

I adjusted the driver current to 900mA. Is it enough to power the A140 diode.
The laser will be powered for long times and I mounted a small cooler fan to dissipate the possible heat from the fins. I'm not expert in adjusting current so I asked the seller to adjust the current to 900 mA, I don't know why I told him 900 mA

900mA is enough to power an a140, but I'm pretty sure they can go up near 1.5a, at 900mA you should be looking at a bit less than a watt of output and pretty much any actively cooled heatsink should me enough for a constant duty cycle.

If I'm not mistaken they can be powered as low as 300mA. I am currently getting all my parts together to build a c6 with a A140. I plan to run it @ 1.25A, and I'm estimating 1.2-1.3w. I got my minimalistic knowledge from the chart I'm linking below. 900mA looks like 900mw.

Don't forget the rep button if this helps you.
