Title: Ultrafast Carrier Dynamics and Nonlinear Optical Properties of Graphene
 
Abstract: 
Due to its exceptional optical and electronic properties, graphene has great potential for optoelectronic applications. These properties, such 
as an ultrabroadband achromatic absorption, few-fs carrier relaxation times and carrier multiplication by auger processes, make graphene an ideal building 
block for devices such as photodiodes, solar cells and saturable absorbers.  Most of these processes, however, are not yet fully understood or even 
experimentally demonstrated. By studying the carrier dynamics of graphene on a femtosecond time scale one is able to completely map the processes through 
which charge carriers evolve within graphene, providing important insight on the possibilities provided by this material. In this talk ongoing work at 
IFIMUP-IN will be presented.
