Abstract
We report an all-fiber high power, single frequency large-mode area (LMA)
linearly polarized ytterbiumdoped 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).
