Help my laser beam is changing size?
My new 200mW 532nm laser torch is doing weird things.
After just a few seconds the beam will turn from a nice dot to a droopy oval.
Is this mod hoping?:yabbem:
Even when it's been off for hours. From a cold state it will do this within 10 seconds. It wil some times focos back to a sharp point for a second, then droop back to a sloppy point.

I also noticed that the beam leaves the final lens at a angle. This is weather the beam is drooping or perfect. In fact I noticed this even before it started drooping.

I'm very sad. This was my second bad luck laser. I'm getting very frustrated
I don't care about being able to burn with a 532nm anymore. I have my O-Like dilda for that. I just want a nice beam for gazing at.

I'm also coming to the conclusion that for some of these lasers with focusing optics are just more trouble then its worth.

I wish I just bought a decent priced module like the 130mW-150mW module from O-Like and a nice host from jayrob or many of the other members who make custom host.
