摘要: Abstract A pulse master-oscillator fiber power amplifier system with china-made large-mode-area and a (6+1)×1 multimode combiner is demonstrated. The generates up to 4.8 W of amplified radiation (100 kHz) at wavelength 1064 nm near-diffraction-limited beam quality (M2=1.2), the overall slope efficiency respect launched pump 50%. Some basic characteristics this system, including pulse-amplification characteristics, gain as well emission spectrum are investigated in detail.
