I know that many of you dreamed to look inside the laser diode.
Today I made a few images of that.
This is NICHIA NUBM44 / NUBM47.
We use 1000X digital zoom
Endurance has made a measurement of the emitting area and we got results in microns (Height X Width): 35+-5% x 250+-5% uM.
The diode with weak light. Corrupted crystal.
