The STELLA research event will be composed of 5 training activities of the duration of 80 hours each, which will be carried out in parallel in five separate laboratories.

Near-infrared ultrashort pulse generation by Kerr-driven OPA

The action is aimed at generating and characterizing both from an experimental and from a numerical point of view ultrashort pulses in the near-infrared obtained via Kerr-mediated optical parametric amplification in different guided configurations.
WP leaders:
Hollow cylindrical waveguide: M. Clerici (experimental), A. Couairon (numerical);
Planar waveguide: A. Gruen (experimental), M. Kolesik (numerical).

High harmonic generation via phase-matched interaction

The action is aimed at an efficient generation of High Harmonics radiation by tailoring of the intense pump pulse. The experimental challenges include control and tunability of the input field as well as the detection of the generated field.
WP leader: D. Faccio.

Ultrashort laser pulse field diagnostic

The action is aimed at the refinement and characterization of a compact, cheap and handy tool for the complete retrieval of amplitude and phase of the electric field of ultrashort laser pulses: this diagnostics involves the use of well-known measurement techniques combined in an innovative way to provide the desired results.
WP leader: E. Rubino.

Second harmonic generation with phase and group mismatch

The action is aimed at investigating and characterizing from a numerical point of view the impact of dimensionality and phase or group mismatch in the process of second harmonic generation in X(2) media.
WP leader: G. Valiulis

Quasi phase-matching in isotropic media induced by pulse modulation

The action is aimed at the theoretical study of quasi phase-matching condition originated by field periodic modulation of ultrashort wavepackets propagating in isotropic media.
