The pulse amplitude of narrow band operating approaches to that of broadband operating, it means that, the energy loss caused by narrowing spectrum is only a few.
窄带运转的脉冲幅度接近宽带运转，这意味着由于谱线压窄引起的能量损耗不大。

A new spectrum shaping method, based on electro-optic modulation, to alleviate gain narrowing in chirped pulse amplification (CPA) system, is described and numerically simulated.
