供应2.0 μm Single-Frequency PM Fiber Amplifier
This 2.0μm single-frequency polarization-maintaining thulium-doped fiber amplifier adopts full-PM all-fiber MOPA design for narrow-linewidth DFB/DBR seed lasers at kHz-level linewidth. Equipped with high-efficiency multi-mode pump sources and double-clad fiber amplification, it steadily boosts low-power input signals while preserving original spectrum and single polarization status with high polarization extinction ratio
