Exceeding 670-mW Linearly Polarized Single-Frequency Fiber Laser Using a 0.6-cm Polarization- Maintaining Yb-Doped Crystal-Derived Silica Fiber

A polarization-maintaining Yb-doped crystal-derived silica fiber (PM-YCDSF) was fabricated, exhibiting a gain coefficient exceeding 5.5 dB/cm at 1030 nm, a birefringence of 6.31×10−5, and a polarization extinction ratio (PER) variation of only 2.1 dB during the temperature range of 20–200 °C. Using only 0.6 cm of activ...
