Cascaded multi-harmonic generation in a \b{eta}-BBO crystal reaching 133 nm from a single 800 nm pump beam
J. Seres, E. Seres, T. Schumm
Nonlinear crystals are widely used to efficiently generate second or third harmonics, and also for frequency mixing. Generation of multiple cascaded harmonics simultaneously, howev…
Probing the surface of silicon and the silicon-silica interface using nonperturbative third and fifth harmonic generation
J. Seres, E. Seres, E. Cespedes +3
We examined, in backward (reflection) geometry, the generation of the 3rd and 5th harmonics, located in the deep and vacuum ultraviolet, on the surface of silicon and on the interf…
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…
All-solid-state VUV frequency comb at 160 nm using multi-harmonic generation in a non-linear femtosecond enhancement cavity
J. Seres, E. Seres, C. Serrat +3
We report on the realization of a solid-state-based vacuum ultraviolet frequency comb, using multi-harmonic generation in an external enhancement cavity. Optical conversions in suc…
High harmonic generation from surface states of solids
J. Seres, E. Seres, C. Serrat +1
We demonstrate that high-harmonic generation (HHG) in solids dominantly originates from strongly localized surface states through non-perturbative processes. Measurements reveal th…
Non-planar femtosecond enhancement cavity for VUV frequency comb applications
Georg Winkler, Jakob Fellinger, Jozsef Seres +2
External passive femtosecond enhancement cavities (fsECs) are widely used to increase the efficiency of non-linear conversion processes like high harmonic generation (HHG) at high…
