The world got its first glimpse of laser technology being used with music back in the 1960’s and 1970’s, when bands like The Who and Pink Floyd, started to use them at their stadium concerts. Lasers created completely new effects, the likes of which audiences had never been seen before. Back then, lasers were very crude in design and very energy inefficient. They needed vast amounts of 3 phase electricity and gallons of water, under pressure, to keep the proteus wheel turning in the exciter or it would cut out. If the laser cut out, it could be catastrophic and it would have taken out the tube, which accounted for almost the entire cost the laser.
Today, however, with the new technology of DP Air Cooled Lasers on the market, lasers are just as powerful, but a lot more stable and affordable. Modern lasers have text animation and graphics packages built into their controllers, so it has become a lot simpler, and cheaper, to produce that very special, unique firework and laser light Show.
