摘要：

Two-colour phase control of gas harmonic generation has been demonstrated using a 200-fs Ti:sapphire laser and its second harmonic. In the detection range covering the 7th to the 20th harmonic order, a modulation of up to 27% in the harmonic emission signal was observed by precisely varying the relative phase between the two colours. Simulations based on the single-particle response predict enhancement of the high harmonic efficiency by orders of magnitude for a given relative phase between the two colours.
