Resonant X-Ray Difference-Frequency Seeding of Inner-Shell X-Ray Lasers
Carles Serrat
We analyze a class of inner-shell x-ray laser systems in which the initial conditions of the emission are set by a resonant x-ray difference-frequency drive. Using a microscopic de…
Parametric attosecond pulse amplification far from the ionization threshold from high order harmonic generation in He
C. Serrat, J. Seres, E. Seres +4
Parametric amplification of attosecond coherent pulses around 100 eV at the single-atom level is demonstrated for the first time by using the 3D time-dependent Schr{ö}dinger equati…
Avalanche effect and gain saturation in high harmonic generation
Carles Serrat, David Roca, Josep M. Budesca +7
Optical amplifiers in all ranges of the electromagnetic spectrum exhibit two essential characteristics: i) the input signal during the propagation in the medium is multiplied by th…
Quasi phase matching for high order harmonic generation induced by the carrier-envelope phase
Daniele Faccio, Carles Serrat, Jose' M. Cela +2
We report a novel quasi-phase matching technique for high-order harmonic generation in low-density gases. Numerical simulations show that in few-optical cycle pulsed Bessel beams i…
Doppler-free Adiabatic Self-Induced Transparency
Yu. Loiko, C. Serrat, R. Vilaseca +3
We demonstrate that a Doppler broadened two-level medium can be made transparent to a laser pulse by an appropriate adiabatic variation of the laser field amplitude and its nominal…
Quantum control of optical four-wave mixing with femtosecond w-3w laser pulses: coherent ac Stark nonlinear spectroscopy
Carles Serrat
The four-wave mixing produced with two ultrashort phase-locked w-3w laser pulses propagating coherently in a two-level system in the infrared spectral region is shown to depend on…
