The Petawatt Field Synthesizer: A new Approach to Ultrahigh Field Generation

Quantum Electron Self-Interaction in a Strong Laser Field

“…Since for long pulses a relatively large amount of electrons will "decay" by radiating, it is convenient to employ here rather short pulses (we have ensured that the asymmetry becomes insensitive to the CEP for longer pulses). Phase-stabilized laser pulses with τ ∼ 5 fs and I 10 22 W/cm 2 are experimentally envisaged [20]. At an intensity of I 0 = 4 × 10 22 W/cm 2 , for example, we find exp[2Im(Φ 0 )] ≈ 9 × 10 −4 and a maximal asymmetry A 0 ∼ 1 % (see Fig.…”

Laser Pulses for Compton Scattering Light Sources

“…State of the art custom systems can produce over 1 PW of peak power, corresponding to for example 40 J in 40 fs. 15,16 Many implementations of the chirped pulse amplification have been demonstrated. Typically, amplifiers consist of high bandwidth laser gain medium, such as Ti:Sapphire or Yb:YAG.…”

Generation and Parametric Amplification of Few‐Cycle Light Pulses at Relativistic Intensities

“…The Petawatt Field Synthesizer (PFS) at the Max-Planck-Institut für Quantenoptik (MPQ) has been designed to deliver sub-two-cycle, high-contrast light pulses for the generation of high harmonics on solid surfaces as the main application [45,46]. To reach the ambitious target parameters -a pulse duration of 5 fs, pulse energies of up to 3 J and a repetition rate of 10 Hz -the concept of this fully OPA-based system contains several key features, which will be briefly explained in the following.…”
