作者演示了在闭环方案中对超短、超强（多太瓦）激光脉冲在空气中传播36m的最佳控制。他们优化了白光连续体中的三个光谱范围以及电离效率。优化结果使目标参数的信号增强了典型的2倍和1.4倍。在白光连续体产生的情况下，优化的结果是通过减少脉冲的啁啾来缩短脉冲，同时从脉冲的缺陷中修正脉冲，并在空气电离的情况下设置探测器附近的起丝点。
The authors demonstrate optimal control of the propagation of ultrashort, ultraintense (multiterawatt) laser pulses in air over distances up to 36m in a closed-loop scheme. They optimized three spectral ranges within the white-light continuum as well as the ionization efficiency. Optimization results in signal enhancements by typical factors of 2 and 1.4 for the target parameters. The optimization results in shorter pulses by reducing their chirp in the case of white-light continuum generation, while they correct the pulse from its defects and set the filamentation onset near the detector as far as air ionization is concerned.
