26 February 1982 Gallium Arsenide Infrared Windows For High-Speed Airborne Applications
Author Affiliations +
Large (7- by 16-inch) plates of semi-insulating gallium arsenide suitable for use as external infrared transmitting windows were grown using a unique compounding process. The plates were grown in an open tube system, the gallium arsenide being solidified from a stoichiometric melt. Detailed growth conditions are discussed. The optical and physical properties of this material are compared with other candidate infrared (IR) optical materials. In addition, some results of captive flight tests comparing gallium arsenide with germanium are given.
