我们报道了二阶衍射引起的超短脉冲角色散的补偿。色差校正的一种策略是利用差形带版的高色散。超平坦色散曲线依赖于一个鞍点，该鞍点可以在规定的波长上调谐。我们的方法的有效性可能达到少周期制度。
We report on compensation of diffraction-induced angular dispersion of ultrashort pulses up to a second order. A strategy for chromatic correction profits from high dispersion of kinoform-type zone plates. Ultraflat dispersion curves rely on a saddle point that may be tuned at a prescribed wavelength. Validity of our approach may reach the few-cycles regime.
