Abstract
More and more experiments involve the interaction of intense few-cycle optical pulses with a second ultrashort optical pulse or an electron bunch. In order to ensure a sufficient temporal overlap, a precise control of the relative timing jitter down to a level of a few fs is required. In the case of intense femtosecond lasers coupled to accelerators, at the photocathode stage or at the beamline stage, the ultrafast oscillator is usually synchronized to an optical or RF electrical reference to a relative jitter below 1fs [1]. Moreover, the additional timing jitter induced by the amplifiers needs to be controlled to the same level of precision. Several compensation systems have already been demonstrated for OPA applications, based on the cross-correlation between the oscillator and the amplifier. Both techniques require a broadband ultrafast oscillator to spectrally encode the temporal drift [2] or to ensure a background-free OPA operation [3]. The proposed solution is compatible with sub-ps oscillators, based on SFG Balanced Optical Cross-correlation [4], in a Non-collinear configuration.
