    Pretty cool.
    Lets see it in action.

    Is it analogue or ttl?

    NICE!!! That red beam looks really fat though. It even seems to surround the other 2 after the "mirror" as opposed to combining with them...

    As ususall... where's the movie??!!! :twisted:

    All lasers are analog.
    All 635nm laser are fat beam.
    671nm is small beam.but expensive and not bright,
    Oh,no,forgot take pictures.movie only.
    Who has server let me upload the movies? (20Mb)
    :P

    Yes.. but your 635nm beam is at least 5 - 10 times larger than your green/blue beams. So that means only 10-20% of the power of the red laser is contributing to the final colour mix....

    I'd personally prefer bucket loads more of 671nm as the beam is nicer, colour saturation is better, and the modulation characteristics would be matched a lot better...

    The red laser of the beam is 3X5mm~3X7mm.

    So that means only 10-20% of the power of the red laser is contributing to the final colour mix
    ....

    Are you fun or never have experience mix the RGB laser ?
    That is 400mw red laser,if only 40-80mw for contributing to the final colour mix.Do you think your consumer accept
    the 900mw RGB system?
    The fact is lost 10%-20%.

    Jian,

    Can't you compress the beam more (635)? By using a external optics?
