Weird 445 output!

There are a couple possibilities. First off is this with or without a lens?

If it is without a lens then its likely a loose window. It is also possible that there is something inside the can itself as also but its less likely than a loose window. Either way I would think your only means of repair would be to do some window surgery (if the rattle occurs when no lens is installed).

Yeah it does it without the lens Blord, I think you're right AP.
Not looking forward to it, another one bites the dust :cryyy:
 
You can try remove the window of the diode. Another method beside opening the can is take a steel pointer of something and crack the glass windows. Do it very gentle. Don't touch anything on the die.
Let the glass shards fall out and you have a windowless diode.
It should solve the problem unless the die itself is damage.

I don't have a choice, thanks Blord, I'll try it today and let you know how it goes. :beer:

Work for my diode I broke it with a sewing needle , Thanks Blord.:p
 
Yeah I should have tried that. I broke the glass but only after prying up the can around the glass.

I don't think glass will melt with our handheld lasers. It needs a lot more energy to do so.
Do you ever been to a glass factory ? The heat needed for melting glass is so intense.

It can happen... I accidentally got some stuff on my 405 nm diode's window, and turned it on, and found the glass had a hole melted right through it. o.o

It's so much energy concentrated in a small area. It doesn't surprise me at all.

Yes look like a hole, but I think that is possible melted dust with the glass superficial coating
 
I would have to go over doing that (in my head) for like 2-3 days before I would actually do it... Good job.
 
Interesting suggestion Blord. I like the idea of cracking the glass and shaking it out. Its less direct destruction to the diode. Though it sounds like that method might sometimes result in glass shards being left stuck inside the can. Either way, modifications to a diode is risky business.
 
I wouldn't do that .. cracking glass can shoot chunks inside, and damage the diode. Did you see those thin wires ? Not mentioning chip front face, which is emitting the light and which exact geometric shape is crucial to laser output and beam cleanness. Glass should be IMHO left intact. Bending or cutting the can is relatively safe.

Yep, even though I was really careful, it killed the diode.
 
Blord, you are an absolute legend mate.

When it didn't work on the 9mm diode I thought oh well you win some you lose some, worth a try.
Last night though I found an old M140 that was throwing off a weird beam too.
As I was going to throw it away anyway I thought I'd try it again.
Well this time it worked perfectly.
It's actually throwing off one of the best beams and dot I've seen from a blue.

You da man! :worthy:

Probably the air oxygen can oxide the diode more quickly but the beam is more powerful to the eye, probably a lot more to the LPM :whistle:.
+1 to Blord and :thanks:
