Vibrational Modes of a Circular Drum Here's an older thread: Some facts about mode-hopping.

It's like new and I have 3 lol so it's not worth extracting it? Btw I'm on my phone, kind of hard to check anything about it and the curiosity just struck me. Thanks for the quick reply!

Im selling this item on eBay, but after reading the specs I was wondering if there is actually a 500mw 1300nm diode in it? If so how much is a diode like that worth? http://bit.ly/GVVZTp

Here's the thread i started to find out what was causing it :P http://laserpointerforums.com/f65/445-diode-extremely-dirty-cleaning-suggestions-67470.html also to de-can i used the electric drill gun + razor blade method.

Like this? Laser oddity. - YouTube I fixed mine by decanning

Well, Decanning Fixed it.

do you think de-canning would fix this problem?

I think the diode is dying or there is something loose in the can, it's weird because i have never dropped it or anything...here's a video...watch. Laser oddity. - YouTube I'm not sure if it was ever dirty to begin with.... best course of action: new diode. lol, right?

I don't know what lens he's using all i know is that my driver is putting out 1.2 amps and by the chart for a140 diodes it says that is about 1100mw (not 1200 like i previously thought), just thought it was a little strange how much better his laser is burning. You have to admit though, it does...

Way better now, but still a little blurry, the acetone definitely helped a lot! thanks guys! https://sites.google.com/site/officialhosting/2011-09-26005.JPG?attredirects=0 by the way, i uploaded this video to youtube, i guessed based off of the amperage vs mw chart that my laser was...

The title says it all, I got a little spec of Arctic silver on the diode, tried cleaning it with no pressure with the tip of a wet q-tip, I really didn't want to scratch the glass on it, and now my output looks like this with no lens...

Hey, I think I already asked you this, but do you own a LPM?

Ill give you $6.50 shipped. without a picture of the damage I dont think anyone wants to take a risk, especially when you're asking 35 for it and it has been soldered who knows how many times. it doesn't sound like you knew what you were doing if it was "your fault". Anyway, my offer stands.

if you show me some pictures then ill admit i stole your idea :) until then it's fair game! hahaha

Ghostchrome, now make a powerful one with it's own case, battery, and relay operated switch.

That would definitely suck! but I did warn him that it is illegal; I'm not just some irresponsible prick like you just insinuated. :-\

hah. Cool, call me out on my advertising methods. I let him know when he bought it three main points, No eyes, no distracting traffic, and no airplanes.

I did! i sold it to some sun valley scumbag; it was a 200mw green also, but it was mode hopping and i didn't want it anymore (i didn't mention that in the ad, but i told him in person). I got 120 bucks for it. More than I expected. I want to see your 522mw DontLazeMe, maybe i could buy...

Dont you just wish it made the sound of a cannon when it goes off compared to the other people's? lol how much did that 400mw set you back?

Just had an epic laser battle for the Nugget casino in downtown Sparks (5 minutes away from Reno), there were at least 25 people with ALL green lasers (most of them were low power ~50mw) shining them on the casino as thousands watched, I must say, thanks to this forum, my 200mw was enough to...
