摘要

We report the first measurement of the stimulated Brillouin scattering (SBS) gain coefficient of a phosphate fiber. Using single-pass amplification of spontaneous Brillouin scattering noise, we measured an SBS gain coefficient of 2.1 × 10~(-11) m/W in a 124.5-cm single-mode Yb~(3+)-doped phosphate fiber. This is a factor of two less than the SBS gain coefficient of silica fiber, which puts phosphate glass fiber at an advantage for high-power applications.
