2W laser big time problem

[DTR]

That driver is boost converter, I measured it and driver did put out 5.5 volts at output

If you connected it directly to a DMM there is a good chance you have damaged it. :yabbem:

You need a test load to figure out what you have and if it does still work to set it to the proper current.

No you need a test load. No better option. You can build one pretty cheap or buy a premade one. Not having a solid secure connection between your diode and driver can lead to diode death like putting a DMM in there.

I think the driver is fckin doomed, Now without filtering cap it starts as previosuly but after few secs starts laser starts to flicker and diode dimms very fast. I guess diode is fine but driver is doomed

If you don't want to deal with setting up your driver grab a driver like a preset X-drive. If you do get an X-drive ditch the filtering cap as I am not sure what that is doing to it and a proper laser driver will not need it.:beer:

At higher than 1,30 amps the diode dimms after 3 secs, I guess this driver is faulty. Anyway, thanks for HUGE help DTR, You always help everybody haha ! Have a nice day

I turned on driver without any load and measured just the volts at output, without any laser diode/
