I WAS THINKING OF A COOL IDEA 8-)
Lets say you have two mirrors that are perfectly parralel to each other and facing eachother like this:
| | -----(=====)
the (=====) is a laser pointer with a beam going towards the two mirrors at a perfectly straight line and in the middle...
The yellow lasers look awesome. Are there any laser pointers with a wavelength slightly closer to orange?
I'd get the 2mW yellow from LASERGLOW but it's too expensive for my budget. Maybe the prices will drop in a year or two.
