摘要:
We report an all-fiber high power, single frequency large-mode area (LMA) linearly polarized ytterbium-doped fiber amplifiers (YDFA) module, which is based on the master oscillator multi-stage power amplifiers (MOPA).The maximum output power is 43.8 W at a wavelength of 1064 nm when 60-W launched pump light is coupled, with high slope efficiency of 88%, polarization extinction rate (PER) >17.2 dB and nearly diffraction-limited beam quality (M2 <1.1).
