Live video journey inside the laser diode with 100 x optical zoom
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 with this digital microscope >>>
Some pictures of the laser diode. Measuring sizes.
Structure of the laser diode
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 (damaged) crystal.
Connecting wires to the crystal (top view)
3 layers: laser diode structure
Wires to the crystal were burned
Sizes of the laser diode.
Size of the emitting laser spot.

Burned diode (burnt threads)
If you have a problem with the laser. It stopped cutting or engraving – remove the lens and explore the laser beam.
A detailed video showing good vs. bad laser beam spot (unfocused)
Excellent diode picture
Another example of a burned (dead) diode (collapsed laser beam form – unfocused)
The rectangle is no longer distinguished.
The rectangle has some damages inside (could happen when the dust hits the exit mirror on the diode and burns on its surface)
