From ebay listings I have found the following mixes....
Laser: Red 200mW & Green 60mW
CONSISTS OF 100MW RED 40MW GREEN AND BLENDED 140-150MW OF YELLOW
Output power: Red 80mW 650nm, Green 40mW 532nm
Output power: 40mW@532nm, 80mW@650nm, Green and Red DPSS laser.
Three-Color Laser: R:200mW@650nm G:80mW@532nm Y:280mW Mixed Yellow
..........so who knows :-/

so that is
3.5 to 1, 2.5 to 1, 2 to 1, 2 to 1 and 1.5 to 1 (all red then green)

Someone may yet come up with a difinitive answer....

but i find it more like 4:1
Click to expand...

I bow to Andy's greater experience, that appears to make 200 red to 50 green about right... I can only say that I have found much lower power green works well....

The ratio is also different with shorter wavelength reds (635nm) which appear much brighter than 660nm. You might be able to get away with a 2:1 ratio. The beam diameter is much larger however making it more difficult to blend colors. Go with analog like Andy said.
