Abstract
We have demonstrated the measurements of attenuation constant of a multi-mode fiber (300μm core diameter and 1km length) at 1070nm. The observed attenuation constant was below 0.7dB/km. The laser power of 5kW was coupled into the 1km fiber at 1070nm. The overall transmittance was 85 %. We observed the first Raman stokes in the transmitted laser spectrum. We demonstrated concrete cutting with a 4kW fiber laser at 1070nm. The demonstrated slab thickness was 100mm. This technique can be extended to thick concrete slabs more than 1m without laser power increasing.
