MLL-Kolloquium: Prof. Uwe Morgner (Leibniz-Univ. u. Laser-Zentrum Hannover): Plasmonic Nanoantennas in Strong Femtosecond Laser Fields

Thursday 1 Feb 2018, 16:00 → 17:00 Europe/Berlin

Lecture hall, ground floor west (LMU building, Am Coulombwall 1, Garching)

In direct vicinity of gold nanostructures, plasmonic resonances can provide an enhancement orders of magnitude beyond the incident laser field. Here, non-linear strong field phenomena can be studied with moderate laser pulse energies directly from a mode-locked Ti:sapphire laser oscillator. Harmonic generation, surface ablation, and a surprising self-optimization of the nanoantennas is observed and analyzed.
