Multi-octave, CEP-stable source for high-energy field synthesis
Abstract
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\,J of energy in two broadband amplification channels and their temporal compression to 6\,fs and 18\,fs at 1\,m and 2\,m, 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 intrinsic 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 free-induction decay after interaction with water molecules are resolved by electro-optic sampling over 2\,ps. The scheme is scalable in peak- and average-power.
