Pushing the M140

[PaulorNuthn]

For you guys that like to push the limits a bit more than most.
Has anyone successfully powered an M140 with a driver set at 2.2A and above?
By successfuly I mean hasn't killed it yet.

If so what was the output on a LPM?
How long has the diode lasted so far if still going?

BTW, I mean set the driver at 2.2A not pushing 2.2W.

Go type "M140 2.2W" in the Google search box above.

Hmm you obviously havent used the search function...:tsk:

Anyway yes, M140's have gone way beyond that...:beer:

 

[PaulorNuthn]

Yeah apologies guys, I usually always try to find out everything I can through the search option, when I have time though.
Sometimes there is nothing better than getting a clear educated answer when you haven't got time as on many occasions I've spent hours sifting through threads and ended up with valued opinions, but not answers.

Eg. Just read a thread which stated there is no use going past 1.8A as the output will be the same, so really we could end up exactly where we started no matter how many threads we go through.

Thanks for the replies all the same gents.

All you have to do is put in 2.2/2.3/2.4/2.5/2.6 W 445 or M140 build...there will be lots of examples of lasers built and LPMed with that power. I don't see where the speculation lies? You'll have the answer staring you in the face and with pictorial and video evidence...

Here are 2 445 builds Ive made:

http://laserpointerforums.com/f65/2-5w-saik-copper-module-pic-heavy-74753.html

They both provide conclusive proof that an M140 can and does exceed 2.2 W, but most of the time you'll need a G lens to achieve it. There have been several notable exceptions though and a couple have nearly broken the 3 W barrier!

My saik build has now lasted more than 6 months and it still has the same output power as the day I built it. If you search further there was a thread started by Gillza about diode longevity, but admittedly not many people have added their details...:beer:

For durability I wouldn't go higher than 1.8A for the M140. I have already repaired two lasers with a M140 set higher than 1.8A and I don't build much lasers with driver higher 1.8A current.

All the lasers with 1.8A or lower never let me down. They are all going strong. Well at least I didn't heard from defect diodes again from the customers.

The 9mm diode will do better than M140 at high current. They seem fine at 2.1 current.

I mean setting the driver at 2.2A
I have a couple at 2.5-2.7W myself but the drivers are set at max 1.85A
Sorry about the confusion.

Thanks Blord, that's exactly the answer I was after.
If its a risk, I'm just not going to try it.

 

[grainde]

Ahh that makes more sense! You had 2.2 W posted!

Here's a thread dealing with that subject: http://laserpointerforums.com/f65/anyone-pushed-m140-beyond-2-0a-75876-2.html :beer:

Why don't you set it at those higher powers and report back. There's a thing called contributing to the forum and this is a perfect thing, running a torture test for the M140 seems something you want to do so do it and let us know how it went all the numbers from low to high will be valued by us all.

Right, because your time is so much more valuable than ours, especially for such a time-critical question as that.

And give me a break. You know damn well that your question could be answered easily by that simple search, and did not require any kind of direct answer that would've otherwise required "hours" of researching. You didn't even put forth the most minimal of efforts into finding the answer yourself. Being a lazy-ass is one thing, being a lying lazy-ass is entirely another.

Sometimes there is nothing better than a person actually going through some effort to find answers for his or herself, if only as a show of respect to those he/she asks questions of.

WTF?
You got some sand in your vagina or something sweetheart?
Seeing as I'm a single dad of 2 kids who works 10hrs a day, and you spend all day on forums getting your purdy knickers in a bunch then yeah my time is more valuable than yours you dammed buffoon.

There you go, I've just answered 1 question you won't have to type into the search.

Please watch your language, if you are a hardworking dad and a man of the world, you dont need need to resort to childish name calling like that.

And yet--somehow--you've got time for your laser hobby. Yeah, we see through that.

Please, no more of these lame excuses. If you're not going to put forth even a minimal level effort, this is not the hobby for you.
