| 摘 要： | 研究了掺镱光纤放大器对中心频率为1 053nm的啁啾脉冲放大特性，发现针对高斯或超高斯脉冲，采用合适的带宽及入射光强能够使增益饱和和失谐放大相互消弱，从而得到一个良好的放大脉冲形状。计算了掺镱光纤放大器失谐放大带来的相位调制，发现对压缩质量影响较小。

| Abstract: | Theory analysis were performed for ytterbium doped fiber amplifier(YDFA) on its characteristics of mismatching amplification on chirped pulse with mid wavelength around 1 053nm. An excellent pulse can be achieved with optimistic input intensity and spectrum width. On the other end, by analyzing the phase mode of YDFA's mismatch amplication, a good result was found. Although the phase modulate was serious, the phase modulate during YDFA mismatch amplification affected the quality of pulse after compression weakly. |
