Advances in Mode Scaling and TMI Suppression in High-Power Fibre Lasers

The combination of high efficiency, high power, excellent beam quality, and low weight make ytterbium-doped fibre lasers a critical component in high-power laser systems. For high power operation, nonlinear impairments such as stimulated Brillouin scattering (SBS) and stimulated Raman scattering (SRS) become limiting factors in further increases in output power beyond a certain limit.
