Inside the laser diode (NICHIA NUBM44 / NUBM47)

Inside the laser diode (NICHIA NUBM44 / NUBM47)

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

Good diode

Burned diode (burnt threads)

 

Excellent diode

Damaged diode

 

 

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)
