摘要：

We investigate the effect of a strong dressing field on the polarizability of atomic helium at harmonic frequencies. This study is carried out in a time-dependent non-perturbative calculation by looking at the harmonic spectrum resulting from the interaction with the combination of two fields: a strong pump field at the fundamental frequency and a weak probe field at some odd harmonic frequency. We present results for harmonic frequencies extending over the characteristic spectrum of high-order harmonic generation.
