M140 diode broken?

Hello

This is my M140 diode picture.

This broken????
:cryyy:

Thats normal

The lines are more pronounced than produced by either of my M140s but they appear normal to me. It is likely just a slight variation of the diode.

Power has decreased to about 30 mw
Everything has been to cut the wires and re-solder the diode. :cryyy::cryyy:

what current is it at?

 

[fermintm]

what current is it at?

1500ma

It worked perfectly until I decided to cut the wires because they were too long.
From there, the laser emits very little light now. I used to have to wear goggles.
I guess the diode has received some electrostatic discharge and therefore this also.

And you are getting 30mw??! It's a zombie then :cryyy:

If. I'm afraid so.

With the crisis we have in Spain, decided to spend some money that cost me a big winner in a laser ...
Now I have a burned diode :banghead: :cryyy: :cryyy:

Possibly not... You said you cut the wires & re attached them, is it connected solid, try tapping the soldering iron quickly & melting it again, also make sure there isn't like 1-2 strands of wire, make sure it's ALL hooked up

 

[Elektrotechniker]

As clear as the picture is, It's hard to tell whether part of the emitter is burnt or not.

 

[fermintm]

Definitely this burned.
The diode becomes very hot with hardly emit light.

 

[Elektrotechniker]

Okay then. yea well if it gets hot it's indeed a LED. sorry about your loss I have lost many 445s during my journey in lasers Others have burnt hundreds..

 

[DTR]

Is it possible after the wires were cut and you were working on shortening them the driver may have been inadvertently powered without a load even for the briefest of time? If so the cap may have charged and spiked the diode when you went to reconnect it.

 

[AnthoT]

Well guess you should just buy a new diode

Maybe you'll get lucky and get a freak one
