Compact Single-Frequency MOPA Using a Silica Fiber Highly Doped with Yb<sup>3+</sup>

We report on a single-frequency fiber master oscillator power amplifier utilizing a polarization-maintaining step-index fiber with an Al/Ce/F core-glass composition doped with a very high Yb concentration (0.25 at.%). This design made it possible to use a very short fiber (~1 m) and to coil it in a...
