If you mean to say, that it's still lasing somewhat after dying, this is exactly what happened with mine...

I plotted it carefully up to 280mA, where it suddenly went dim. But not as dim as i am used to with other diodes when they die (and only an ugly blob remains). When i looked at it closer, it was evident, that some lasing is still being done, but only at 11mW (still using 280mA of current but at a slightly reduced Vf)!

You can see the graph and comments here...



The only thing this diode is now useful for is to de-can it and take a super-macro of the die for comparison....
