I should also mention that the combinations that involve blu-ray really mess with your eyes. The beams look great but you know how when you look at a blu-ray dot it seems to be way bigger and have a bunch of noise around it? You get that effect going on with only the blu-ray so the dot will end up magenta or aqua with a bunch of stuff going on around it, it is very weird and eye straining even at low powers.

I have heard that beam is more stable if i use red laser more than green laser, so what about blu-ray and green,which i have to use more to reach stability? :-?

Your eye is most sensitive to green, followed by the 650 red and 404 violet comes in last place.

With yellow you probbably need around twice to four times more red than green.  Blu-ray and green is more of a dilemma.  To the eye, you are going to need 20 times or even more 404 than green, but a camera will be looking for a ratio closer to 1:1 since cameras are insanely sensitive to 404.

Red and violet are similar to green and violet, you are going to need substantially more violet than red unless you are taking photos.

So i will get blue beam just combining 5mw green and 100mw violet

My picture with the violet/blue was done with a PHR at 130mA and a 5mW green module. For the camera, I had to turn the PHR way way down but for the beam to actually look like the pictures in person I just left them each running full power. The green is just so much brighter to your eye its incredible.

i think i will buy phr-803 sled and 20x dvd burner sled from ebay, 50 mw dpss green module from O-like and then take optics out of the  sleds for blue and yellow color

I'm going to put all tree lasers on same case and make each lasers power easily adjustable with three knobs outside closed case and also add three buttons outside the case so i can power on lasers i want and adjust power ''on fly''. I put optics inside the case and make beams go throught the optics with mirrors(anybody know good mirrors :-? ) so i can make color i want

I have some of the 1''x1'' mirrors from user koanna4 on ebay, that I used for a laser project. They work very well.

Ships only in USA? I live in Finland

Keep in mind that you don't necessarily need mirrors, I just used one because I am planning a very very compact pointer layout and it was necessary to have a mirror for alignment.

If you just position the lasers at 90 degrees to begin with you should be ok.

I gave red+green a really quick whirl today:

I used a CD case to reflect the green (MarioMaster's idea).

On my todo list is a yellow labbie similar to 691175002's. I don't know if I'll be able to include color tuning abilities (totally awesome idea by the way), though.
