  negative chirp
Consequently, we have succeeded in compressing the chirped pulses to 13?fs by compensating the intrinsic negative chirp.
      
Chirp effects of the fundamental laser on the pulse width of the fifth harmonic were consistent with the negative chirp of the fifth harmonic.
      
When the pulse energy is lowered to about 400?μJ the yield maximum at negative chirp vanishes and only the maximum at positive chirp remains.
      
We also detect chirp modulation with a negative chirp rate corresponding to powerful dissipation of electric current in the CML during a solar flare.
      
As the signals propagate in the HNL-PDF, the positive dispersion serves to compensate the negative chirp.

The spectral feature of chirp pulse in normal dispersion fiber was experimentally researched,the experimental results were numerically calculated,the experimental results were agreed with the numerical calculation results. the following results were obtained by the experimental and calculation method:the pulse width in the frequency domain would be changed when the input mean optical power was big enough;the bigger the input mean power was,the larger the pulse width in the frequency domain would be changed.

负啁啾脉冲在正常色散光纤中的频域特性进行了实验研究,并对实验结果进行了数值分析,实验和数值分析结果基本一致.

Based on a newly developed general quantum theory of nonlinear optical pulse propagation, the change of the squeezing ratios are studied as the propagation of the optical pulse with initial chirp in the normal dispersion Kerr media. Numerical results show that the squeezing still survives, but the squeezing is weaker in the normal dispersion media than in the anormal dispersion media and the initial negative chirp is benefit for squeezing.
