For the first time, Raman gain spectra are measured for three all‐glass Yb:YAG crystal‐derived optical fibres. It is shown that fibres derived from YAG have a reduced Raman gain relative to that of pure silica, partly because of a significant broadening of the silica Raman lines, and also partly because of yttria and alumina possessing a lower gain than that of silica. Such a designer‐materials approach for suppression of stimulated Raman scattering can enable future high‐energy and high‐peak‐power fibre laser systems.
