"Those are laser diodes that are normally used for "laser speed guns" and similars ..... very fast, 0.5nS response time and usuallly used at 200nS pulses lenghts ..... this means that they can hold the 10W for 0.2mS max, normally at 100 Hz max rate or similar (cooled) ..... and, usually, this also means that in CW conditions, you can get from them around 50mW ..... after this, *POOF" "
