What is 'threshold'?
I assumed it was the point when ANY light was given off by a diode but looking at Sams faq I might well be wrong and that it is the point when actual lasing starts.
If it is indeed the point when lasing starts it might well explain why I blew up a 5mW diode as Sams faq seems to be saying that the maximum current for the diode is only 10% past the threshold. I.e if the threshold is 30mA then the diode maximum current would be just 33mA. Is this correct?
I hope the above makes sense and would very much appreciate it if anyone can clear this up for me to save a repeat disaster.
One last thing. What sort of current should a 5mW red diode be taking? I have no spec sheets or part number nor do I know the make.
Many thanks - Dave
