Abstract

Experiments to transmit a 1kW COIL laser beam of 1.31μm wavelength and a 5kW fiber laser beam of 1.07μm wavelength through glass fibers 1km in length were conducted. Three types of fiber from different companies were tested, and the minimum pure loss observed was 15% per km. A Raman component was detected in the 5 kW experiment.
