Paper Abstract

Design of a scanned laser display system is described. The equipment presents a full-colour large screen TV display of 525 and 625 line standard using off-air or recorded video signals. It has two lasers as light sources, an Argon laser providing green and blue primary colours, and a dye laser pumped by excess power from the Argon laser, providing the red primary. The design stresses efficiency in the use of laser power to achieve a bright image. The advantages of scanned laser display systems, including inherently good colour and resolution, are discussed in compari-son with light valves and CRT-based displays. Present and future applications of laser displays are noted.
