First build, yellow laser.

Yep i would just use the optics from a phr or ps3 sled; it will save you a bunch of money

ow, I thought that if i connect the 2 laser modules paralel that each laser get 4.5v.

You have it drawn in series, not parallel. As long as they both add up to 9V anyway, it should work, but greens are 3V, and reds are... well, that really depends on the driver.

uhh.... I thought there was a yellow laser diode.... guess I was wrong...

There might be a yellow diode out there somewhere for some type of equipment but it would cost $$$$$. A yellow DPSS laser will be cheaper than any yellow diode. And combining green and red to make yellow is even cheaper than a yellow DPSS.

you cant power it with a 9v battery it will break the diodes you need a 3v battery pack for each module or you can power it off one if you wire them in parallel
