What is "arrilaser"

The Arrilaser is a digital film recorder made by Arri which writes digital movie files onto film after compositing and audio mastering on the computer. Files are sent to the device via a fast gigabit Ethernet connection. The Arrilaser uses three solid-state lasers (red, green, and blue) as a light source, and significantly reduces the cost of recording digital images onto film. Its chief competitor is Celco's Film Fury CRT-based recorder. As of July 2009, there were more than 250 Arrilasers installed worldwide.
