Rare-earth doped fibers for high power fiber amplifiers normally have a small refractive index difference between the core and inner cladding, but have a larger core diameter than conventional telecom fibers. We take advantage of this feature as well as the difference between the optical and acoustic waveguides and proposed several fiber designs to mitigate Stimulated Brillouin Scattering (SBS) to...
Ge-doped laser fibers with suppressed SBS are proposed. By taking advantage of the difference between optical and acoustic properties, higher SBS thresholds of 3-5 dB are shown numerically while maintaining diffraction limited beam quality.
In this paper, we discuss the design of optical fibers with tailored acoustic speed profiles to suppress stimulated Brillouin scattering in high-power, single-frequency sources. We demonstrate the ability of these fibers to achieve single-mode output powers of greater than 500 W and discuss the potential to achieve powers beyond 1 kW.
