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 >>>

Improve your 3D printer / CNC with the Endurance laser

Endurance has made a measurement of the emitting area and we got results in microns (Height X Width): 35+-5% x 250+-5% uM.

Good diode

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.

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)
