IEEE Journal of Selected Topics in Quantum Electronics, 2018 Single crystals or glasses that are doped with light emitting atoms are used as the gain medium in solid-state lasers. In crystals, the atoms exist in the form of ions. Aside from conventional rods and slabs with lengths of several cm, technologies based on disks or fibers with thicknesses, respectively diameters of 10 to 100 µm become more and more ...

High Power Laser Science and Engineering, 2023 In this work, we experimentally investigate the dependence of the stimulated Raman scattering (SRS) effect on the seed linewidth of a high-power nanosecond superfluorescent fiber source (ns-SFS). The results reveal that the SRS in the ns-SFS amplifier is
