Lecture

Ultrafast Phenomena

Description

This lecture by Fabrice Carbone presents ultrafast experiments to study materials and their modifications in response to a light pulse on a femtosecond timescale and nanometer resolution. The experimental setup uses a femtosecond laser to create red and ultraviolet light paths, where the red light excites materials and the ultraviolet light generates electron pulses for imaging. By adjusting the delay between the light and electron pulses, high-resolution movies of material responses to light excitation can be captured, providing insights into the elasticity and mechanical properties of materials, such as graphene thin films.
