A 100 μm fiber-coupled diode end-pumped configuration is used to generate a fundamental emission wavelength that strongly depends on internal resonator losses. Stokes emission at 1096 nm is achieved with a slope efficiency of 42 ± 8%, an optical conversion efficiency of more than 32% and a maximum output power of 4.5W for quasi-continuous operation (1 ms pulses). The explored Stokes conversion of 89 cm−1 shows excellent laser characteristics, indicating that this still little explored Stokes shift could pave the way to continuous-wave Raman frequency-comb lasers.1-4openAccesslasersraman effectdoped materialssolid state lasersraman spectrastokes parameterswavelengthscrystalsArtigo de periódico12110.1016/j.optlastec.2019.1058350000-0002-9379-9530https://orcid.org/0000-0002-9379-953075.4281.00
