由於非線性脈衝傳播，雷射雜訊如能量、時間、相位及頻率上的擾動均已在實驗上被詳細分析。我們的結果證明出利用色散遞減光纖達到時域上脈衝壓縮的結果，將降低雷射的本質特性，如上述所提及的雜訊分析。
另一方面，脈衝在色散遞增光纖傳遞時，造成頻譜壓縮，其結果將導致雷射在絕熱光孤子系統下，及雜訊特性保持原樣，甚至比原本雷射本身好。本文將顯示出以鎖模雷射為光源，改變不同的入射啁啾脈衝，在色散遞增光纖中進行非線性脈衝傳遞前後的特性比較。

Laser noise properties such as amplitude, timing, phase and frequency jitters as a result of nonlinear pulse propagation are experimentally characterized. Our results show pulse propagation in a dispersion-decreasing fiber (DDF) for pulse temporal compression leads to noise degradation. On the other hand, pulse propagation in a dispersion-increasing fiber (DIF) for spectral compression maintains its noise properties in an adiabatic soliton system. In the numerical analysis, it might be possible that the noise such as an amplitude jitter will never change as propagating in dispersion-increasing fiber (DIF). In the experiment, we show that different input chirped pulses may keep their noise properties with the pulse propagation through the DIF.
In the calculation, we analyze the amplitude jitter of the fundamental soliton through the single mode fiber (SMF) first and then point out that the same concept is suitable for the DIF. Experimentally, using the mode-locked fiber laser (MLFL) as a source, the laser noise properties will not change as propagating through the DIF in an adiabatic soliton system.
