I remember I saw a laser pen in the past that used to make a noise when you press the momantory button it's like there is a mini cooling fan inside the pen or similar to low noise laser systems, that was in 1991,the beam was dim red probably around 680nm wavelength I'm guessing, not sure about the output though . So is it possible to use a micro cooling fan in a laser pen? I know what I heard when I placed the pointer next to my ear..
Check on ebay you could get one less than $ 100 just make sure its including the lamp and the rod, also try to get the rod already with mirrors at the ends for less hasleRe: Nader
If any one wants capacitors you can get any volt with any size for good price you can get them from ebay, usually they offer discount on price as a pack of 10 or more.

I meant the diameter of the rod is small about 2 mm I guess
Just got a question, what's the best way to hook up the flash tubes from the disposable cameras if I want to align them parallel to the laser rod? I have a 50mm long rod but very small did the seller told me I can use a standard flash from the disposable camera unit by using one or two capacitors which should be enough to fire the rod. I'll wait for a reply Re: Nader
