High-intensity delivery of CO laser (λ ≃ 5.4 μm) power by an AS2S3chalcogenide glass optical fiber is reported. Transmission of 4-W cw power is achieved in a 200-μm core diam unclad fiber without any deterioration. Light intensity of 12.8 kW/cm2at the fiber output was attained. Use of this power for various applications, especially medical, is discussed.
