The amplification of 20-fs-duration pulses in an amplifier with spatial dispersion in the gain medium (dye) is theoretically analyzed. Pulse self-shaping was observed during amplification, and further shaping was achieved by spatially modulating the pump. This spatial modulation of the pump permits the elimination of pulse broadening in the amplifier, even in the saturation regime. The possibility of using a compound medium with an ultrabroadband gain profile is also discussed.
对增益介质（染料）中具有空间色散的放大器内20飞秒持续时间脉冲的放大进行了理论分析。在放大过程中观察到了脉冲自整形现象，并且通过对泵浦光进行空间调制实现了进一步整形。泵浦光的这种空间调制能够消除放大器中的脉冲展宽，即使在饱和状态下也是如此。还讨论了使用具有超宽带增益谱的复合介质的可能性。
