High-power Yb-doped Fibre Laser for Cutting Dry Pine Wood

This article reports experiments on the laser wood-cutting performance of a 1 kW ytterbium fibre laser a recent, compact, flexible, efficient laser system. The cutting process is characterized, taking as a reference the effects of the principal process factors. A quantification of energy consumption during the cutting process, critical for scale-up, is provided.
