Abstract

Infrared interferometric systems using a CO2 laser operating at a wavelength of 10.6 μm are described. Specific systems discussed are a Twyman-Green interferometer and a Twyman-Green interferometer with an infrared computer-generated hologram (IRCGH). The reduced sensitivity due to the longer wavelength enables us to test optical components necessary for IP high-energy laser systems. This paper also illustrates typical results obtained from testing infrared trans litting materials, diamond-turned metal mirrors, and aspherics. Special alignment techniques and basic limitations of infrared interferometry are discussed.
