Abstract

For quasi-phase matching of high-harmonic generation at short wavelengths, a beat-wave pulse train with 66-fs pulse separation is generated from a two-color Ti: sapphire amplifier system. By using such pulse train to collide with the main driving pulse for harmonic generation in the interacting media, quasi-phase matching can be achieved. The 66-fs pulse separation matches to a quasi-phase-matching zone length of 4.9 μm, which corresponds to a dephasing length for 3-nm harmonic generation under 1.0×1018 cm 3 plasma density. The pulse train energy is 100 mJ, sufficient to support more than 1000 quasi-phase-matching zones.
