A compact multicore ytterbium doped fiber amplifier has been implemented according to the spectral division scheme. It was shown that it allows amplification of pulses with about 40 nm wide spectrum. Compensation of the different spectral bands delay through bending and twist of the multicore ribbon fiber followed by appropriate setting of their phase permitted the synthesis of pulses close to 100 fs duration.
已根据光谱分割方案实现了一种紧凑型多芯掺镱光纤放大器。结果表明，它能够放大光谱宽度约为40nm的脉冲。通过对多芯带状光纤进行弯曲和扭转来补偿不同光谱带的延迟，然后适当设置它们的相位，可以合成持续时间接近100fs的脉冲。
