Coherent instabilities in thulium-based fiber amplifiers induced by laser frequency modulation

A Pertoldi, JM Hauge, P Bowen Montague… - Optics Letters, 2024 - opg.optica.org
Frequency modulation of narrow-linewidth lasers can cause coherent backscattering in
cladding-pumped fiber amplifiers. This detrimental effect can be observed in Tm-based fiber …
