hey everyone,
yes, i asked that on cpf already, with no response at all.
reading the thread how many LDs everyone killed so far, i have hope you have suggestions!
so.. more or less, every laserdiode would die at a different point, depending on parameters not visible (for normal people). like most LDs would die from COD, catastrophal optical damage, which is burnt/melted end-facets due to too high laserpower (inside the cavity).
is there any chance to see that the LD is at its limit? coherence length, modehopping or similar? how complicated it would be to see isnt important, i would test a LD once only, to guess its limit, and then use it some under that limit.
perhaps its not possible at all, if the parameters of the LD change gradually/linearly/exponentially only, and then simply stops to lase altogether.
again, i volunteer to try your suggestions, and blow some LDs on it.
