What I mean is that as you increase power there is a point where the laser suddenly drops in power and then recovers a little bit later on. It is a small area where the laser losses power. There is a device made by the same greek company that makes eyemagic scanners that can correct for this. It is $800.00 so I never bothered. I just use a laser big enough that I have the power I want below the lasers knee. For me 500mw is a lot of green. I only have 1watt blue and 800mw red so I use maybe 200mw-300mw of green max. In my living room that is a lot of power. Heck I remember when I only had 125mw total from my argon and 35mw from my hene on a pcaom. So no complaints from me. I must say gas lasers and a pcaom made for a lot better beam quality. I still miss perfectly aligned colors and no color tails of any kind. You could also go for an AOM and not worry about it at all.
