似噪音脈衝具有光滑且寬頻的光譜、皮秒及飛秒兼具的雙尺度脈衝寬度和在時域上振幅隨機變化的脈衝陣列等獨特性質，為了更進一步了解似噪音脈衝的行為並發展其應用，我們使用全正色散摻鐿光纖雷射振盪器並連結全保偏光纖放大器，振盪器可產生輸出功率為173毫瓦、雙尺度脈衝寬度分別為13皮秒及312飛秒、且頻譜寬度為18.23奈米的似噪音脈衝。除此之外，我們安置一色散延遲器於雷射腔外來研究似噪音脈衝的色散性質。實驗結果顯示，似噪音脈衝的基底和較窄的內部結構均可於時域上被壓縮，最佳的壓縮雙尺度脈衝寬度分別是4.75皮秒及226飛秒，其對應的壓縮比率分別為2.68和1.38，而脈衝內部結構的時間-頻寬乘積為0.684，接近高斯波形的最短脈衝 (transform-limited pulse)。在放大過程中，不同泵浦功率下的光譜寬度維持約20奈米。最終我們定性的解釋實驗結果。

Noise-like pulse (NLP) presents unique features such as smooth and broadband optical spectra, double-scale intensity autocorrelation (AC) traces and stochastic amplitude of pulse trains in the time domain. To further comprehend the behavior of noise-like pulse for applications, we utilized an all-normal dispersion (ANDi) Yb-fiber laser followed by fiber amplifier stage using polarization-maintaining (PM) fibers. The oscillator generated noise-like pulses with pedestal width of 13 ps, spike width of 312 fs and spectral width of 18.23 nm. The average output power was 173 mW. Additionally, a dispersive delay line (DDL) outside the cavity was employed to study the dispersion properties of noise-like pulses. The results revealed that the temporal compression of pedestal and coherent spike of noise-like pulses is feasible. The best-compressed width of pedestal and spike were 4.85 ps and 226 fs, with the compression ratio of 2.68 and 1.38, respectively. The estimated time-bandwidth product (TBP) of coherent spike was 0.684, which is close to the transform-limited pulse of Gaussian profile. During amplification, the spectral width remained ~20 nm for different pump powers. Finally, the experimental results have been qualitatively explained.
