    I beleive it should have read:
    "the most powerful full color solid state laser display", as that is what the 38W one was spoken of at LDI 2009... I think.

    Let's discuss this. According to http://en.wikipedia.org/wiki/Laser_L...nd_Coulee_Dam)

    "Lasers for the show are projected from the nearby Visitor's Arrival Center and consist of four large frame Coherent Sabre Lasers, (two 12-watt Krypton (red) and two 30-watt Argon lasers (green and blue). They are split and combined with dichroic filters and controlled with analog modulators to create full color vector images."


    What would everyone estimate for losses from age, dichros, polarization, AOM's and other internal optics? Also, there are two scanner sets inside... The power stated in the wiki is the label power for the lasers and does not account for these losses. Back in the 80's it was common practice for companies to ignore these power losses when rating a system.

    Just for reference, I've attached a picture of the Coulee Dam laser.

    lol, sorry eliav but that picture you posted of the coulle dam laser is just plain SEXY!!!! 66 watts or not, the coulle dam has ya beat in sexiness!!!

    that is a beautiful beam table!!

    Glad to hear that's a thing of the past now...

    Only 2 problems with the Grand Coulee Dam laser show

    1. You need a hydroelectric dam to power the lasers.

    2. No Dark Side Of The Moon laser shows.

    Awesome lasers though!!

    and here was the response

    George,

    Congratulations on your creation of a truly remarkable projector. Packing 66.2 Watts of color output in a projector that size is very impressive. However, we are not quite ready to give up our title as creators world’s most powerful full-color laser systems.

    To the best of our knowledge, the two most powerful RGB laser projectors ever created – with 84W of RGB output each – are the Laser Fantasy Rainbow projectors we created for the Grand Coulee Dam in Washington State and for Riverscape Park in Dayton, Ohio. The Laser Fantasy Rainbow projector at the Grand Coulee Dam <http://en.wikipedia.org/wiki/Laser_Light_Show_%28Grand_Coulee_Dam%29> was first installed in 1989, and the Rainbow projector at Riverscape Park was installed in 1999. The Grand Coulee system – now maintained by a former employee of ours who lives near the dam – recently finished its 21st season of nightly shows and is expected to operate indefinitely into the future; the Riverscape system operated reliably for a decade of regular shows before the projection building was repurposed last year for other uses. (We also believe the Grand Coulee Dam system comprises the largest graphic projection surface of any type in the world.: covering an area that is 150m tall and more than 1.25km wide, we project images on a “screen” that covers a stunning 200,000 m^2!)

    These Laser Fantasy projectors consume roughly 200kW of electrical power per system and more than 200 liters per minute of cooling water, and weigh close to two tons apiece – as such, they probably rank as the least portable laser projectors ever created! Compared to your compact and efficient OPSL-based projectors, our ion-based Rainbow systems may seem like beasts. However, with 84W of RGB power and a divergence of less than 0.17mrad, we believe they remain not only the most powerful RGB projectors ever created, but also the only viable option for extremely long projection throws.

    Yours is undoubtedly the World’s Largest Full-Color OPSL-Based Entertainment Laser, and it will certainly find great use in the many situations where the facilities requirements of our larger ion-based systems are just not practical.

    Best Regards,

    -Alex

    In response to what was posted from the ILDA list...
    It's not 84 watts of output, as Alex said, but 84 watts rated internal power when built... They use two 12-watt Krypton and two 30-watt Argon laser.
    After many years (21 as of now), and a serious amount of optics, I'm fairly certain that you wouldn't get 84 watts if you put a meter at the scanners - both of them...
