Chalcogenide Glasses for High Energy Laser Applications
Abstract
Substantial reduction in the absorption at 10.6 micrometers is required before chalcogenide glasses can be used with high-energy CO2 lasers. In this program, new methods for compounding high-purity TI-1173 glass (composition Ge28Sb12Se60) and TI-20 glass (composition Ge33As12Se55) were developed. At the present stage of purity, the absorption for TI-1173 at 10.6 micrometers is about 0.01/cm. The absorption is dominated by the silica content of the glass and can be lowered if the impurity is removed. The absorption for TI-20, however, is presently about 0.05/cm and is dominated by a broad, low- level absorption centered about 12.8 micrometers. The absorption appears to be intrinsic, and little can be done to improve TI-20 further.
