There were 45 custom DMX controlled diode lasers provided by Tarm. The lasers were interconnected via daisy-chaining involving just a single cable that transmits both the necessary drive power and the DMX signal. “There were three trusses in the rooftop, and there we mounted a matrix of 3 x 7 lasers, so we had a total of 21 from the front and 21 from the top and an additional three beside the LED panel to cover all the Airstage balloons,” explains Kwasny.
Those lasers were compact; approximately the size of a baseball. “The laser diode is just like a thumbnail. It’s like nothing. The output of the laser is 1.4 watts and the wavelength is 450 nanometers, which means it’s in the deep blue range,” notes Kwasny. Mounting them on the lighting trusses proved to be a challenge. “The trusses in the roof were not straight, they were slightly curved, and so to be on one line, we used 21 of the Magic Arms from Manfrotto.” The lasers behind the LED wall were mounted on an existing structure via custom clamps created by tarm Showlaser GmbH. www.tarm.de
