“…On the basis of this scheme, in 2018, Rossi et al (32) boosted the energy of the light transients to nearly 1 mJ by using a 20-mJ, 1-kHz, 150-fs Ti:Sa amplifier to (i) generate multi-octave seed pulses and (ii) pump the two parallel OPCPA channels. In a follow-up experiment, Mainz et al (33) demonstrated the effect of the shape of the generated light transients on HHG yield. However, boosting the energy and average power of light transients beyond this value calls for a different frontend due to the limitations of simultaneous energy and power scalability in Ti:Sa amplifiers (34).…”

These authors contributed equally to this work.The development of high-energy, high-power, multi-octave light-transients is currently subject of intense research driven by emerging applications in attosecond spectroscopy and coherent control. We report on a phase-stable, multi-octave source based on a Yb:YAG amplifier for light-transient generation. We demonstrate the amplification of a two-octave spectrum to 25 µJ of energy in two broadband amplification channels and their temporal compression to 6 fs and 18 fs at 1 µm and 2 µm, respectively. In this scheme due to the intrinsic temporal synchronization between the pump and seed pulses, the temporal jitter is restricted to long-term drift. We show that the intrin-1 arXiv:1911.00545v1 [physics.optics] 1 Nov 2019 sic stability of the synthesizer allows for sub-cycle detection of an electric field at 0.15 PHz. The complex electric field of the 0.15 PHz pulses and their freeinduction decay after interaction with water molecules are resolved by electrooptic sampling over 2 ps. The scheme is scalable in peak-and average-power. TeaserWe report on a novel source for generating high energy, sub-cycle pulses based on a Yb thindisk laser.
