چکیده انگلیسی
A stable mid-infrared supercontinuum (SC) generation with a maximum average power of 8.76â¯W in a spectral band of 1.9-2.65â¯Âµm is reported. To broaden the bandwidth of SC, a 1.55â¯Âµm pulsed laser system delivering 1â¯ns pulses at a pulse repetition frequency of 500â¯kHz was used as a seed source for one-stage thulium-doped fiber amplifier. The power conversion efficiency for wavelengths longer than 2.4â¯Âµm and 2.5â¯Âµm was determined to be 28% and 18%, respectively, which is believed to be the most efficient power distribution towards the mid-infrared in SC sources based on Tm-doped fibers. The power spectral density of the continuum was calculated to be >13â¯mW/nm with a potential of further scaling-up. A long-term power stability test, showing power fluctuations <3%, proved the robustness and reliability of the developed SC source.
