【 摘 要 】

Intense nanosecond four-colour Fourier-synthesized laser fields induce orientation-selective ionization based on directionally asymmetric molecular tunneling ionization. The interferometer-free laser field generator ensures high stability and high reproducibility. Phase-sensitive, orientation-selective molecular tunneling ionization provides a simple way to estimate the relative phase differences between the fundamental light and each harmonic by data-fitting analysis.
