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.

Third harmonic generation in Kerr media

The action is aimed at performing theoretical, numerical and experimental activities for achieving efficient third harmonic generation in centrosymmetric Kerr media by means of quasi-phase matching (QPM) techniques.

Generation of coherent X Waves via cross-phase modulation in Kerr media

The action is aimed at performing theoretical, numerical and experimental activities for achieving generation of single, coherent, X waves of controllable phase and group velocity in centrosymmetric Kerr medium.

Characterization of plasma channels generated by Bessel beams versus Gaussian beams/filaments and THz generation.

The action is aimed at performing theoretical, numerical and experimental activities for identifying the operating conditions capable of creating a laser-induced plasma channel in a Kerr medium of maximum regularity (maximum length, constant electron density in the propagation direction, and minimum transverse size.
WP leaders S. Tzortzakis, D. Papazoglou, A. Couairon

Generation of field-stationary conical waves

The action is aimed at performing theoretical and numerical activities for identifying operating conditions suitable for generating nonlinear conical waves which can propagate having not only stationary envelope but also stationary field profile.
WP leaders A. Couairon, M. Kolesik

Generation of coherent X waves in X(2) materials with Gaussian pump beams

The action is aimed at performing theoretical and numerical activities for identifying operating conditions suitable for generating single coherent X waves in X(2) media, and studying those regimes which support spatiotemporal focusing of the generated X wave during free-space propagation over suitable distance.
