Higher power lasers and optics.

I'm pretty new to lasers and only have a 50mW Ebayser and a ~100mw red DIY laser.
In both cases now the dot is really untidy, it this a problem confined to higher powers as when they are turned down these imperfections become less visable?

When I say untidy, I mean that around the central bright spot, there is what I would describe as a red/green 'haze' which is amplified with distance. (Hence my lovely DIY red looks horrible when projected maybe 10-20m onto a white wall)
If I were to buy a more expensive unit with glass optics would this likely solve these problems?

It's probably just a dirty lens. So just take a search around and find some different ways to clean them.

Probably, maybe I should use a fog machine instead of cigarette smoke ::)

I hate smoking! :D But a fogger is a great investment, I still don't have one but my neighbor does so I just take his all of the time. I'm tempted to see if I can find a good deal on a hazer. A good option to help keep your lens clean would also to get/make a flat cap when using fog so it doesn't get directly on the lens of your laser.

Regarding beam visibility, i've been running an ultrasonic humidifier the last few days. I can tell the difference between when it's on and off. yeah, there's a nice mist around the unit that does great things for a beam, but after about 15 minutes, the beam visibility doubles or tripples in the house AWAY from the unit.

Yeah, what works really well in my house is:
After having a nice hot shower, keep the door closed and try out your laser :D
The humidity really highlights the beam!
I'm going to try make some effects soon using the motors out of all the CD drives I tore apart ::)
