We demonstrate a front-end of an Yb-based passively CEP-stable, two-octave wide, two-channel optical parametric synthesizer driven by slightly sub-picosecond pump pulses from a multi-mJ regenerative amplifier at 1 kHz.
The phase and stability characterization of white-light supercontinuum generated by sub-picosecond pulses at 1 μm in YAG and sapphire for different pump focusing and duration shows compressible pulses, suitable for applications like waveform synthesis.
We present a phase-stable, multi-mJ 3-channel parametric synthesizer generating 2-octave-wide waveforms (0.52–2.4 µm). After two amplification stages, the combined 125-µJ output supports 1.9-fs waveforms. The energy is scaled to 2 mJ after three amplification stages.
The coherent synthesis of custom-tailored, intense, sub-cycle optical waveforms is promising for attosecond science and strong-field physics, e.g., for precision control of strong-field interactions in atoms, molecules and solids, for the generation of intense isolated attosecond pulses, and for attosecond pump-probe spectroscopy.
We demonstrate a phase-stable, 3-channel parametric synthesizer generating a 2-octave-wide spectrum (0.52–2.4μm). After two amplification stages, the combined 125-μJ output supports 1.9-fs waveforms. The third stage of the IR degenerate OPA yields 1.7-mJ octave-spanning spectra.
We generate 800-nm, sub-7-fs pulses from a degenerate Optical Parametric Amplifier pumped by the second harmonic of a Ti:sapphire system and seeded by supercontinuum generated by a near IR OPA pumped by the same source.
