Default Help my laser beam acting funny

My new 3 day old 200mW 532nm started acting funny last night
It would change size and flicker in brightens.
Now to day it's gotten worse it will do this within seconds. from a cold state.
It looks like crap. it becomes a droopy dot with a whole mess of scatter.
Shining on a wall 8ft away it blends in to one big 12-inch scattered mess
It has become completely unusable.

I never even used the laser longer than 15 to 30 seconds at a time.
Is this mod hopping? What can I do.
This is my second laser from rayoss. The first one died within 24 hours.
Now this one. I was very carful to follow the instructions from rayfoss. About not using it for longer than 60 seconds at a time.
WTF This sucks

I don't know if I should even tell rayfoss. I'm so disappointed.

this is called "mode hopping"

And its best to go with o-like .com

Their green modules are VERY dependable ^_^ i own 3 and NONE of them have EVER mode hopped.

it sucks that it was a 200mW laser... and not a 50mW one. You can get 50mW ones for like 30 bucks. i would DEFINATELY contact rayfoss, as it should only modehop after about 30seconds to be considered a normal effect of heat.

Jayrob knows allot more about it than me, but we recently had a conversation about this very issue. and he sais a few of his mode-hop after 30-40 seconds as well, but you say yours is hopping after only a few seconds???

And i truely think it may be defective. honestly, rayfoss is known for having very good customer service "not as good as Susie's from o-like though " im sure they would be willing to at LEAST repair it, if not send you a new one. its always worth a shot brother, good luck!

I also BUILD high quality reliable green lasers with custom heatsinks in pocket sized hosts. PM me if this is something that interests you friend ^_^

Default Re: Help my laser beam acting funny

I would be only able to ask them for a repair as of now.
I took it apart. When I reasembled it. I didn't screw down the spacer far enough.
When I screwed the main head back on it whent down to far and scratched the first lense on the tip of the actual laser modual
Now with that small scratch the beam picks up that scratch and looks like real crap.

I would ask you to do a custom build. Just a little worried you might have way too much work, piling on on your plate. At ten dollars a build you must be having them coming in by the boat load

Not really,

I am currently taking orders. the list in my build thread is really more of an organization tool for me, and also to keep the customers updated. So give it some thought

I am also able to work with the larger IR filtered green modules that range from 200-500mW's possibly higher.

I can also work with the less expensive 30mw-150mW modules. These have incredibly narrow tight beams that are perfectly focused. And the way the host's i use are built, theres no way for you to destroy anything, you could take it apart and examine it if you wish. everything will be plug and play.

Shoot me a PM sometime,

Dark
