Thank you for sharing, do note though that you've already been asked not to double post. That's what the edit button is for.
That's not the issue.It's fine if you have a current-balancing resistor on each diode. 1-2 ohms is typical for high powers.
Huh? If the diodes are in parallel, and the driver is set to output a constant current, failing open is the problem.Only if the diode were to fail short. That pretty much never happens.
Whoops, you are correct. I've edited my post above. They don't really fail open either. They just quit lasing. I've never had a laser diode fail either open or short. Maybe if a wire came loose, but that would be bad no matter how many diodes you were powering.Huh?...
So they're not already mounted on C-Mount packages?I have three of these 15W laser diodes now, I will probably mount them in their own C-Mounts, active cool them and then combine the outputs somehow.
I've got a prototype buck PCB en-route that will do 120 mA to 5A range, set via multi turn potA buck driver is definitely the way to go here. The community is in need of a driver which can output more
