Abstract

Optical components which highly reflect the hydrogen fluoride (HF) overtone wavelengths (near 1.3 micrometers ) and transmit or absorb the HF fundamental wavelengths (2.6 to 3.1 micrometers ) can be used to obtain high intensity 1.3 micrometers radiation with HF chemical laser technology. This paper describes the development of the HF overtone laser resonator mirrors. Also presented are the designs of the coatings for laser resonator and the optical performance results for the coatings which includes separated coatings that are highly reflected in 1.3 - 1.4 micrometers wavelengths and highly transmitted or low reflected in 2.6 - 3.1 micrometers wavelengths and the double band antireflection coating for 1.3 - 1.4 micrometers and 2.6 - 3.1 micrometers .© (1996) COPYRIGHT SPIE--The International Society for Optical Engineering.
