Abstract

Combining the concept of temporal field synthesis with optical parametric chirped pulse amplification (OPCPA) holds promise for generation of multi-mJ, watt-level light transients, which may extends isolated attosecond pulse to multi-keV photon energies [1, 2]. The details of our proposed conceptual architecture of such a field synthesizer is described in [3]. The apparatus consists of (i) an Yb:YAG thin-disk regenerative amplifier, followed by (ii) phase-stable multi-octave seed generation, (iii) amplification of three complementary portions of the supercontinuum in OPCPA channels, and (iv) coherent combination of the output of these channels.
